Definitions
- the present invention relates to an optical device for augmented reality, and in more detail, it is possible to significantly reduce the size, thickness, weight and volume, and provide a clearer image for augmented reality by effectively blocking ghost images and at the same time providing a wide viewing angle. It relates to a compact augmented reality optical device having a capable ghost image blocking function and a wide viewing angle.
- Augmented reality means providing a virtual image or image provided by a computer or the like superimposed on an actual image of the real world, as is well known.
- an optical system In order to implement such augmented reality, an optical system is required that allows a virtual image or image generated by a device such as a computer to be superimposed on an image of the real world and provided.
- a technique using optical means such as a prism for reflecting or refracting a virtual image using a head mounted display (HMD) or a glasses-type device is known.
- HMD head mounted display
- conventional devices have a limitation in that the virtual image is out of focus when the user changes the focal length when gazing at the real world.
- a configuration such as a prism that can adjust the focal length for a virtual image is used, or a variable focus lens that can adjust the focal length for a virtual image according to a change in the focal length for the user's real world is electrically controlled.
- Such techniques have been proposed.
- this technology also has a problem in that a user must perform a separate operation in order to adjust the focal length for a virtual image, or hardware and software such as a separate device, processor, etc. are required for controlling the focal length.
- the applicant of the present invention is a device capable of implementing augmented reality by projecting a virtual image on the retina through the pupil using a reflector having a size smaller than that of a human pupil, as described in Patent Document 1 Has been developed.
- FIG. 1 is a diagram showing an optical device 100 for augmented reality as disclosed in Patent Document 1 above.
- the augmented reality optical device 100 of FIG. 1 includes an optical unit 10, a reflective unit 30, an image output unit 40, and a frame unit 60.
- the optical means 10 is a means for transmitting at least a part of the actual object image light, which is the image light emitted from the actual object, and may be, for example, a spectacle lens, and a reflective unit 30 is embedded therein. In addition, the optical means 10 transmits the augmented reality image light reflected from the reflecting unit 30 to the pupil.
- the frame unit 60 is a means for fixing and supporting the image output unit 40 and the optical means 10, and may be, for example, a frame.
- the image output unit 40 is a means for emitting augmented reality image light, which is an image light corresponding to an image for augmented reality.
- augmented reality image light For example, an image for augmented reality is displayed on a screen to emit augmented reality image light. It may be provided with a collimator (collimator) for collimating the image light to be a parallel light.
- collimator collimator
- the reflection unit 30 provides an image for augmented reality by reflecting the image light corresponding to the image for augmented reality emitted from the image output unit 40 toward the pupil of the user.
- the reflective part 30 of FIG. 1 is formed to have a size smaller than the size of a human pupil, that is, 8 mm or less.
- the depth of the incident light can be made almost infinite, that is, the depth of field can be made very deep.
- the depth of field refers to the range recognized as being in focus.
- the focal length of the image for augmented reality increases. Therefore, the user gazes at the real world. Even if the focal length for the world is changed, the focus of the image for augmented reality is always recognized as correct regardless of this. This can be seen as a kind of pinhole effect. Accordingly, it is possible to always provide a clear virtual image for an augmented reality image regardless of whether the user changes the focal length while gazing at a real object existing in the real world.
- this technique requires an additional optical means such as a collimator for parallel light in the image output unit 40, so that the size, thickness, and volume of the device are increased.
- a method of performing the function of a collimator by embedding and arranging a reflective part such as a concave mirror inside the optical means 10 without using a collimator in the image output part 40 can be considered. According to the configuration, there is an advantage in that the size, thickness, and volume of the image output unit 40 can be reduced.
- FIG. 2 is an augmented reality optical device 100 in which the augmented reality optical device 100 of FIG. 1 is provided with a collimator in the image output unit 40 and an auxiliary reflector 20 that performs the function of a collimator. This is a comparison of the side view of -1).
- the image output unit 40 is composed of a display device 41 and a collimator 42, and the augmented reality optics on the right side of FIG. It can be seen that the device 100-1 is configured with only the display device 41 without the image output unit 40 without the collimator 42.
- the augmented reality optical device 100-1 on the right side of FIG. 2 does not use the collimator 42 for the image output unit 40, but is in the form of a concave mirror that can perform the function of a collimator inside the optical means 10.
- the auxiliary reflection unit 20 of the is disposed, and the augmented reality image light emitted from the image output unit 40 is reflected by the auxiliary reflection unit 20 and then transmitted to the reflection unit 30, and the reflection unit 30 ) Transmits the transmitted augmented reality image light to the pupil.
- the augmented reality optical device 100-1 as shown on the right side of FIG. 2 performs the same function as the augmented reality optical device 100 of FIG. Since the configuration is not used, there is an advantage in that form factors such as size, volume, thickness, and weight can be significantly reduced compared to the augmented reality optical device 100 using an external collimator as shown in the left side of FIG. 2.
- the augmented reality optical device 100-1 as shown on the right side of FIG. 2 has a problem in that unintended real object image light that generates a ghost image can also be transmitted to the pupil.
- 3 is a diagram for explaining the principle of generating a ghost image in the augmented reality optical device 100-1.
- the actual object image light which is the image light from the actual object, is directly transmitted to the pupil through the optical means 10, while there is a miscellaneous light reflected by the auxiliary reflector 20 and transmitted to the pupil.
- the actual object image light transmitted to the pupil by the miscellaneous light is formed in a different position from the actual object image light transmitted directly to the pupil through the optical means 10, thereby generating a ghost image.
