Description

Screen stereo microscope system realizing high-definition stereoscopic images {Screen system for 3D opaque microscope}

The present invention relates to a screen stereoscopic microscope system that implements a high-definition stereoscopic image in which a stereoscopic image is realized, characterized in that a stereoscopic image magnified by a microscope is observed on a large screen in high definition without an afterimage.

Substance refers to the real thing, such as minerals, semiconductors, and biological tissues, not preparat. A conventional stereoscopic microscope means that individuals view individual samples through their respective microscopes. Therefore, the microscope image that the teacher sees and the microscope image that each student sees are different.

Substances such as semiconductors and electronic circuits in engineering colleges, precise operating structures such as minute clocks, and real samples and actual surgical images that cannot be seen with preparat, such as skin surfaces and surgical areas in medical colleges, are displayed on a super-large screen 10 times or more than 100 times. The need for a large number of people to observe the enlarged image in 3D at the same time has emerged.

A stereoscopic image is based on the difference in vision seen by the left and right eyes of a person. That is, the brain recognizes the difference in the deflection angle due to the distance between the left and right eyes, and feels a three-dimensional effect. Therefore, if the left and right deviation of the stereoscopic image is smaller than the distance deviation between the left and right eyes, the three-dimensional effect is reduced.

Moreover, when observing a stereoscopic image magnified 10 times or more and 100 times as in the present invention, the deviation is further magnified.

Therefore, when a stereoscopic image is projected on a screen, the deviation becomes larger, so a precise brown image can be converted into a natural stereoscopic image on a screen with a screen size of 80″ or more and 300″ that can be viewed by 10 to 300 people at the same time in a classroom or lecture room. Observation skills are needed.

As a prior art related to this, there is Korean Patent Application No. 10-2003-0051854, but this prior art could not implement a stereoscopic image on a large screen as a stereoscopic image that the human eye sees. In addition, since the method for configuring the distance between the left and right CCD cameras to be close to the left and right eyes of a person is not presented, it is not possible to obtain a natural three-dimensional effect as when a person directly observes. Since the resolution of water could not be maintained and afterimages such as ghosting occurred, observation of microscopic images, especially clear stereoscopic images, was not achieved, so it was not put to practical use.

Another prior art, Korean Utility Model Application No. 20-2002-0003563, relates to a wide-field, high-brightness screen imaging system, but this also could not be applied to microscope images. Stereoscopic images cannot be realized on a normal screen. That is, the polarization degree of the left and right images for stereoscopic is separated and the left and right images are separated and reflected to realize a stereoscopic image. It is a structure that expands the That is, it is the opposite function to the function of separating and reflecting the degree of polarization. Therefore, it was impossible to implement a stereoscopic image itself.

As a conventional technology for expressing stereoscopic images, there is a technology of Korean Patent Application No. 10-2011-7012726, but this is a 3D image signal transmission method and an image display device, and two image sensors are configured at a distance of 65mm of human binocular parallax. There is no specific technical presentation for application to a stereoscopic microscope such as the present invention, only a general and common sense explanation is presented.

Republic of Korea Patent Application No. 10-2003-0051854 Republic of Korea Patent Application No. 10-2011-7012716 Republic of Korea Utility Model Application No. 20-2002-0003563 Korean Utility Model Application No. 20-1995-0007937

They are separated in each direction and projected onto the surface of the surface reflective screen.

The left and right images incident on the surface reflection screen 303 are separated and reflected from the surface reflection screen, and the left and right images separated and reflected from the surface reflection screen are natural three-dimensional viewing at the distance (A) between the left and right eyes of a person.

Describing the present invention in more detail, as shown in FIGS. 1, 2, and 3, the objective lens system 100 has a stage 101 and a lighting device 105 added to one side of the stage 100, and the stage 101 The support 102 provided vertically at the rear, the up and down moving table 104 that moves up and down inside the support, and the left and right image sensors provided at the front end of the up and down moving table 104 and converting them into electronic signals. It consists of (114,115).

It is composed of left and right incident lenses 112 and 113 that input images to the monitor 108 and the left and right image sensors 114 and 115 in front of the support 102, and the left and right objective lenses 110 and 111 and the left and right projectors (202,203 ) system and a surface reflection screen 303 that reflects on the surface.

As shown in FIG. 2, the objective lens system 100 consists of left and right rectangular optical axes (l, r), and the left optical axis (l) includes the left objective lens 110, the left incident lens 112, and the left image sensor ( 114), and the right optical axis r is composed of a right objective lens 111, a right incident lens 113, and a right image sensor 115.

That is, the interior angle (∠A) formed by the left and right optical axes (l, r) and the common focus (G) is less than 15 degrees.

In the present invention, the image incident on the left objective lens 111 at the common focus (G) is incident on the left image sensor 114 through the left incident lens 113, and the image of the left image sensor 114 is incident on the left projector 202 ) and the image of the left image sensor 114 incident on the left projector 202 is polarized by the left polarizer 204 and is incident on the surface 301 of the surface reflection screen 303.

The image incident on the right objective lens 110 is incident on the right image sensor 115 through the right incident lens 112, and the image of the right image sensor 115 is incident on the right projector 203 and is transmitted to the right projector 203. The incident image of the right image sensor 115 is polarized by the right polarizer 205 and is incident on the surface 301 of the surface reflection screen 303.

The polarization direction of the left and right polarizers 204 and 205 is composed of left and right symmetric square directions. That is, if the left polarizer 204 is 45 degrees to the left, the right polarizer 205 is configured to be 45 degrees to the right. The polarized glasses 302 used for this are also configured in the same direction.

2(a) and 3, the image of the left projector 202 reflected from the surface reflection screen 303 is incident on the left polarizer of the observer's polarizing glasses 302 and is incident on the observer's left eye, and is incident on the right eye of the observer. Since the image of the projector 203 is incident on the right polarizer of the observer's polarizing glasses 302 and is incident on the observer's right eye, the observer sees the left and right images separated from the left and right.

That is, the substance of the observed object observed through the joint focus (G) is separated from the microscope image by the left optical axis and the microscope image by the right optical axis, and is reflected on the surface of the surface reflection screen 303, and then converted to the left and right polarization angles, respectively. Since the left image is incident on the left eye and the right image is incident on the right eye separately through polarized glasses of the observer, the observer observes a stereoscopic image.

In the present invention, the left and right incident lenses 110 and 111 are provided on top of the left and right objective lenses 110 and 111 and the left and right image senses 114 and 115 are provided thereon, but the left and right incident lenses 112 and 113 and the left and right images are provided. The left and right spacing (A) of (114,115) is based on 65mm

The left and right distance (A) of the present invention can be applied within 60 mm or more and 70 mm or more in consideration of the difference between people.

The left and right objective lenses 110 and 111 configure the left and right optical axes (l, r) as up-and-down squares based on the left and right intervals (A) so that the focal point formed at the bottom becomes one common focus (G), but the square Configure the joint focus (G) at the position where the lower end coincides, but set the length to 250mm, which is the visual distance of a person. is configured to be within 15 degrees.

Therefore, since the left and right deflection angles of the left and right objective lenses 110 and 111 must also be within 15 degrees, from the joint focus (G) through the left and right objective lenses 110 and 111 and the left and right incident lenses 112 and 113, the left and right The total optical axis length up to the image sensor (G) is composed of 250mm.

The structure of the left and right objective lenses 110 and 111, which have a left and right deviation of 15 degrees at the optical axis distance of 250 mm, provides a stereoscopic image by natural left and right deviation, as if seeing a real object at a visual distance of 250 mm based on the human eye. do.

Variable multiplication of the magnification of the inverted lens 117 or the left and right objective lenses 110 and 111 that inverts the top and bottom of the image between the left and right incident lenses 110 and 111 and the left and right image sensors 114 and 115 within a visual distance of 250 mm A lens 116 may be added as needed.

In the present invention, the left polarizer 204 is provided at the front end of the left projection lens 206 of the left image projector 202, the right polarizer 205 is provided at the front end of the right image projector 203, and the left polarizer 204 and the right polarizer 205 are provided. The polarization directions of the polarizer 205 are formed at mutually symmetrical angles. That is, if the polarization direction of the left polarizer 204 is 45° in the left diagonal direction, the polarization direction of the right polarizer 205 is 45° in the right diagonal direction.

The projection angle of the left and right projectors (202.203) is configured so that the left and right distances of the left and right images projected on the screen are the same or within 65 mm.

That is, when the left and right projectors 202 and 203 are provided in two stages up and down, the central axis of the projection lens composed of up and down is configured to coincide, or when the left and right projectors 202 and 203 are configured in the left and right directions, the left and right projectors 202 and 203 It is to configure the projection lens interval of 65mm or less.

If it is out of this range, the distance between the left and right images on the screen is enlarged so that it can be viewed in double image, and it is impossible to implement 3D images. The configuration of (202, 203) produces an effect of imaging the left and right visual difference of the stereoscopic image magnified on the surface reflection screen 303 within the distance between the human eyes, so that natural stereoscopic image observation is possible even on a large screen.

As shown in FIG. 3, the surface reflective screen 303 has a reflective surface and forms scattering rays 304 scattered in left and right directions on the reflective surface. That is, scattering rays are formed in one direction on the reflective surface.

The reason for this configuration is that the left and right images polarized in the left and right symmetrical square directions are polarized and reflected at the surface reflection screen 303 in opposite directions, for example, the left image is polarized and reflected at an angle of 45 degrees to the left, and the right image is This is because they are deflected and reflected at an angle of 45 degrees to the right, so they do not overlap each other and are reflected separately from the surface of the surface reflection screen 303 /

In general screens, the degree of polarization is absorbed and scattered on the surface, and less than about 1% of the degree of polarization is reflected, making it virtually impossible to realize 3D images.

Since the present invention is reflected on the surface of the surface reflection screen 303, the polarization degree is maintained up to 90% compared to that of a general screen, so that the left and right images are separately reflected without ghosting or afterimages, so that the image is 90 times clearer than before. 3D images can be provided.

In this way, the distance between the left and right images of the left and right projectors 202 and 203 formed on the surface reflection screen 303 is set to be less than 65 mm.

If it is more than 65mm, it is because it is wider than the left and right eye distance that the brain is empirically recognized, so fatigue or headaches occur easily.

As shown in FIG. 3, the surface reflection screen 303 is composed of a white metal surface such as aluminum, chrome, silver, and stainless steel and has a reflectance of 2% or more and 30% of the surface reflectance, so that the left polarizer 204 It consists of a polarization reflection surface reflection screen 300 capable of separate reflection of microscope images from the postal light plate 205 while maintaining each degree of polarization.

This surface reflection screen 300 is composed of a reflective surface having high reflectivity in the upper and lower directions as shown in FIG. 301) should be formed on the surface of the reflective surface. For example, if fine hairlines with a thickness of 50-100 microns are formed in the vertical direction so that the scattering direction is left and right, a reflective surface with high reflectivity is formed as a whole while maintaining the scattering function of the screen that forms an image. am.

The reason for this configuration is that the function of the general screen itself is mainly to form an image projected on the scattering surface. This is because the image itself must be clear and the left and right polarization degrees must be clearly separated and reflected when a detailed stereo microscopic image is implemented as a stereoscopic image as in the present invention.

In addition, this surface reflection screen 303 is polarized in left and right symmetric squares by the left and right polarizers 204 and 205, and separates the polarization angle of the projected stereoscopic image in the left and right directions, but while calculating the image, This is because it reflects efficiently on the lower reflective surface.

That is, when the polarizer is provided so that the image direction of the left and right polarizers 204 and 205 is polarized in the vertical and horizontal directions instead of the symmetrical left and right squares, only one of the left and right polarized images is displayed on the surface reflection screen 300. This is because it is reflected from the surface, making it impossible to implement 3D images.

Therefore, according to the present invention, a plurality of system configurations act as one system, and a stereoscopic image is implemented as a stereoscopic screen as it actually operates in real time on a super-large screen with a diagonal of 80″ or more and less than 300″.

Since the surface of the surface reflective screen made of a metal material like the present invention is strong, it has excellent reflective properties. Therefore, since the image polarized by the polarizer is reflected while maintaining 90% or more of the polarization degree, microscopic images without afterimages can be observed in three dimensions.

As shown in FIG. 3, the maximum transmittance of this polarizer is 50%. Since the brightness of the left and right polarizers 204 and 205 provided at the front end of the left and right projection lenses 206 and 207 respectively decrease by 50% and the polarization glasses 302 by 50% respectively, the overall brightness is 25% (1/4) compared to the 2D image. is lowered to

In the present invention, the maximum reflectance on the surface 301 of the surface reflective screen 303 is a reflectance of 30%. The reflectance of a normal screen is less than 1%. Considering that the total transmittance of the polarizing film is 1/4, the present invention increases the brightness up to 30 times, so even if it is reduced in the polarizing film, the total brightness becomes more than 7 times, so it is possible to provide high-definition stereoscopic images in a bright room. .

In the present invention, as shown in FIG. 3, the size of the surface reflection screen 300 can be projected from 80″ to 300″ diagonally, so that 16² = 256 times to 60² = 3600 times magnified compared to 5″, which is the size of the image field seen with a conventional microscope. It enlarges the image to a large screen and presents microscopic 3D images with high definition that is 2 to 30 times higher than that of the existing screen, and it is possible to provide a screen with uniform brightness without hot spots. Therefore, it is possible to educate and observe from 10 to 300 people at the same time in a bright place.

In addition, in terms of its action and effect, microscopic images of living insects, ores, and crystals magnified by 10 to 100 times are displayed on a super-large surface reflection screen 303 of 80″ or more and 300″ from 256 to 3600 times magnified screen 2 With a 30-fold brighter image, it is possible to observe a moving object as a 3D stereoscopic image, similar to seeing a moving object with the distance between the left and right eyes of a person.

The present invention acts as a whole in which the structure of the objective lens, the incident lens, the image sensor structure, and the components of the surface reflection screen are organically combined with each other, so that the objective lens and It is possible to observe precise and clear 3D images without afterimages on the large surface reflection screen 303 while passing through the video camera and polarized left and right projectors.
