An optical system with an entrance pupil, has a first aperture diameter, an exit pupil and a reflective or transmissive filter element spaced at a distance from the entrance pupil, which is designed and arranged such that a second diameter is illuminated on the filter element by a beam passing through the entrance pupil and spreading divergently from this. The second diameter corresponds to n times the first aperture diameter, and n is a number greater than 1, as a result of which the local angular spectrum at each point on the filter element is n times smaller in comparison to the entrance pupil. The filter element selectively reflects or transmits to the exit pupil at each point only a predetermined spectral range. An optical imaging unit comprising the filter element is provided, which images the entrance pupil onto the exit pupil.

A waveguide for a detector system includes a transparent main body with a partially transparent incoupling region and a decoupling region that is spaced apart therefrom in a first direction. The incoupling region includes a diffractive structure which deflects only part of radiation coming from an object to be detected and impinging on the front face such that the deflected part propagates as coupled-in radiation in the main body by reflections up to the decoupling region and impinges on the decoupling region. The decoupling region deflects at least part of the coupled-in radiation impinging thereon such that the deflected part exits the main body via the front face or rear face in order to impinge on the detector system. The extent of the incoupling region in a second direction transverse to the first direction is greater than the extent of the decoupling region in the second direction.

A screen includes a transparent base body with a front face and a rear face, and an image sensor. The base body includes a coupling-in region and a coupling-out region at a distance therefrom in a first direction. The coupling-in region includes a diffractive structure which deflects only part of the radiation incident on the front face and originating from an object to be detected, such that the deflected part is propagated as coupled-in radiation in the base body by reflection, until it reaches the coupling-out region and is incident on said coupling-out region, and the coupling-out region deflects at least part of said incident coupled-in radiation, such that the deflected part exits the base body via the front face or the rear face and is incident on the image sensor.

An imaging apparatus has a plurality of light-emitting elements arranged in a first direction along a line for generating a plurality of modulated light beams wherein the plurality of light-emitting elements comprises a plurality of optical elements, which are arranged in the first direction, and a laser projector apparatus for scanning the optical elements in the first direction. A deflection apparatus is included for adjustably deflecting the plurality of modulated light beams in a second direction, wherein the second direction differs from the first direction; and wherein the deflection apparatus comprises a rotating element and the optical elements are arranged on the rotating element.

Data projection system

A device for data projection, includes a holographic element arranged as a imaging element for a windshield. An imaging device has a first imaging system and a second imaging system configured to illuminate the holographic element. The holographic element has a first volume hologram structured to be angle-selective for light under a first illumination angle and to generate a first two-dimensional virtual image at a first fixed distance from the holographic element corresponding to the first image data, and a second volume hologram structured to be angle-selective for light under a second illumination angle and to generate a second two-dimensional virtual image at a second fixed distance from the holographic element different from the first distance corresponding to the second image data, such that the first and second images are viewable separately and simultaneously by a person.

Methods and devices for data projection

A functionalized waveguide for a detector system includes an incoupling region of a main body that deflects only part of the radiation coming from an object to be detected and impinges on the front face such that the deflected part propagates as coupled-in radiation in the main body by reflections up to the decoupling region and impinges on the decoupling region. A decoupling region deflects at least part of the coupled-in radiation impinging thereon such that the deflected part exits the main body via the front or rear face to impinge on the detector system. The extent of the incoupling region in a second direction transverse to the first direction is greater than the extent of the decoupling region in the second direction. In the second direction, the incoupling region has at least two different diffractive incoupling structures which have a different deflection component in the second direction.
