Definitions

  • the present invention relates to an arrangement, in particular for generating an optical image, and a camera system with such an arrangement.
  • a sharp, bright and low-distortion image can also be achieved from large fields of view.
  • beam deflection is required for very large fields of view (> approx. 160°). If this is done with mirrors, there are either gaps in the field of view or unused areas on an image sensor, which is used to record the recording, for reasons of principle and design.
  • an objective 24 comprises a lens 26 and an aperture arrangement.
  • the terms camera array and multi-aperture system are common for arrangements such as that shown in FIG. 4 .
  • a multi-aperture system usually designates a multiple lens arrangement whose image falls on a single image sensor.
  • One object of the present invention is to provide an arrangement for generating an optical image, the arrangement being of compact and simple construction.
  • the gist of the present invention is to have recognized that it is possible to avoid gaps in the field of view or unused areas on an image sensor used by connecting a multi-aperture lens to a prism assembly, so that for on the prism assembly incident light rays there is a compression of the angular spectrum.
  • the proposed arrangement comprises a multi-aperture objective for generating an optical image, and a prism arrangement, the multi-aperture objective being connected to the prism arrangement in order to form an arrangement of optical channels.
  • the prism arrangement has one or more refractive indices which is or are greater than that of air, so that an angle spectrum of the light beams incident on the prism arrangement is compressed.
  • the prism arrangement can also be referred to as a prism array.
  • the prism arrangement comprises two or more prisms.
  • the multi-aperture lens includes two or more lenses.
  • each prism is assigned an objective of the multi-aperture objective.
  • this does not mean that a prism must be assigned to each lens. Rather, it is conceivable that no prism at all is assigned to one or more lenses, ie a subset of lenses, while all other lenses outside of this subset of lenses are each assigned their own prism.
  • a prism is assigned to each lens. In other words, this means that the number of prisms arranged next to one another in one plane is less than or equal to the number of lenses.
  • the prism arrangement preferably consists of a refracting medium which has a refractive index.
  • the refractive index is greater than one (refractive index n>1), in particular the refractive index is n>1.3.
  • the refractive index of the refractive medium is n>1 or particularly preferably n>1.3.
  • the refractive indices of two prisms can be different.
  • the refractive indices can be different when two prisms surround an objective.
  • the advantage of a prism over a surface mirror is that when a light beam enters the prism, the angular spectrum of the same is compressed, but is expanded again when it exits. This effectively leads to an extension of the beam path.
  • This extension creates space on the side of an optical channel for the deflection of the adjacent channel.
  • the light beam can be deflected on one of the side surfaces of a prism, for example by total reflection at the glass-air transition. It is also conceivable to apply a metallic and/or a dielectric coating to the prisms, as a result of which the optical channels can be separated from one another and as a result reflections in the corresponding prism are made possible.
  • a further aspect of the present invention relates to a camera system which includes an arrangement as proposed herein and an image sensor which is connected to the arrangement in order to record an image.
  • the image sensor can also be a detector which can detect different electromagnetic wavelengths.
  • a field of view can be imaged on an image sensor that is larger than a space of a hemisphere. This is because the proposed prism arrangement allows the outermost prisms to have optical channels which capture light beams which lie behind the arrangement or behind the camera system.
  • the term “behind the arrangement” or “behind the camera system” in the present case means that objects can also be imaged by the arrangement, which are arranged, for example, laterally and thus perpendicularly to an extension plane of the arrangement.
  • the proposed camera system or the proposed arrangement can cover an even larger field of view than half a space without the camera system or the arrangement growing significantly. Furthermore, the costs for producing such an arrangement or such a camera system do not increase significantly either.
  • the proposed arrangement or the proposed camera system can be used in vehicle cameras.
  • Other example areas in which the proposed arrangement or the proposed camera system can be used are robotics, machine vision (in other words: machine vision using industrial cameras), remote sensing, mobile phones, in video conference systems or in medical applications.
  • the arrangement described here is particularly suitable for multi-channel camera systems with a narrow spectral range, since a medium with a refractive index n>1 is used for the beam offset described, ie the compression of the angular spectrum of incident light beams.
  • the refracting medium used can have wavelength-dependent dispersion.
  • Applications with a narrow-band spectral range can be found, for example, in night vision cameras in the near infrared with narrow-band IR illumination, in time-of-flight cameras with modulated VCSEL illumination, in laser scanners with point, stripe or line projection, or in SWIR cameras (SWIR is an abbreviation for short-wave infrared light).

  • Each of the lenses 24 has a central viewing axis 70 .
  • the central viewing axis 70 runs perpendicularly to an extension of the multi-aperture objective 20, in particular parallel to a z-direction as shown in FIG.
  • each prism 32 forms a section of an optical channel 22 in which the angular spectrum is compressed.
  • a light beam deflection or the path of the light beam 34 in the corresponding optical channel 22 can be assigned to the prism 32 by an image sensor 40 .
  • a height of the two or more prisms 32 is preferably designed to be the same.
  • a prism 32 can have a trapezoidal or a triangular base.
  • the prism 32 in FIGS. 1 to 3, in which the optical channel 1 is arranged has a trapezoidal base, while the prism 32 in which the optical Channel 2 is arranged, has a triangular base. It is also conceivable to use an m-cornered prism, where m is a natural number between 3 and 12.
  • the present technical teaching is based on the principle that the angular spectrum of light rays 34 is compressed depending on their wavelength in a refracting medium when passing from air into the refracting medium, provided the refractive index n of the refracting medium is greater than one. Because a ray of light that strikes at an angle ⁇ to the perpendicular falls out in the refracting medium at a smaller angle ß. So if a lens collects rays from a certain acceptance angle, i.e. there is a maximum angle of incidence, this is smaller in the medium. In the present case, the term "compression of the angular spectrum" was chosen for this situation.
  • the prisms 32 or the refracting medium have a refractive index n greater than one, preferably greater than 1.3.
  • the refractive indices of two prisms 32 are different from one another.
  • the principle proposed here is based on an arrangement of the optical channels 1 and 2 without prisms 32 according to FIG.
  • the optical channels 1 and 2 have a large channel spacing from one another, with the fields of view of the first and second optical channels 1 and 2 adjoining one another.
  • the distance between the optical channels 1 and 2 is therefore fully gear taken up. Reducing the channel spacing without introducing a prism vignettes light rays, resulting in a cropped field of view where the channels' fields of view would no longer be adjacent to each other.
  • the introduction of prisms compresses the angular spectrum, resulting in unused space between the optical channels that can be used to reduce the distance. As a result, the sensor area can also be better utilized.
