Abstract: A functionalized waveguide for a detector system and a lighting and/or projection system includes a transparent base body. A first outcoupling region deflects at least a part of the incoupled radiation hitting the first outcoupling region, such that the deflected part exits the base body via a front side or a rear side thereof in order to hit the detector system. The extent of the first incoupling region in a second direction perpendicular to a first direction is greater than the extent of the first outcoupling region in the second direction. The base body has a second outcoupling region, which deflects at least a part of light from a light source or image source hitting the second outcoupling region as illuminating radiation, such that the deflected part is used for illumination and/or projection.

Abstract: A waveguide includes a partially transparent incoupling portion, having a decoupling portion spaced apart therefrom in the lateral direction, having a substantially transparent base body outside the incoupling and outcoupling portions. The transparent base body has front and rear sides, the wave guide having a diffractive incoupling structure in the incoupling portion and a decoupling structure in the decoupling portion, the diffractive incoupling structure configured to diffract radiation coming from an object and incident on the incoupling portion only in part such that the diffracted part propagates to the decoupling portion by reflections in the base body as incoupled radiation, The decoupling structure deflects part of the incoupled radiation such that the deflected part exits the base body in the decoupling portion via the front or rear side as decoupled radiation, and the diffractive incoupling structure has a diffractive efficiency which continually decreases toward one edge of the incoupling portion.

Abstract: An imaging module of a projection device generates a multi-color image such that a first color sub-image with a first wavelength and a second color sub-image with a second wavelength are generated. Deflection efficiency curves for a specified angular range about a specified viewing angle are set such that a first efficiency ratio for the specified angular range is constant. The imaging module is actuated such that when the multi-color image is generated, a first brightness ratio of the brightness of the first color sub-image to the brightness of the second color sub-image is inversely proportional to the a efficiency ratio such that different deflection efficiency curves are compensated for and such that the viewer can perceive the multi-color image as a true-color virtual image at viewing angles from the specified angular range.

Abstract: 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.

Abstract: A projection unit images a multi-color image having a first and a second wavelength into an exit pupil such that an observer can perceive said image as a virtual image when an eye of the observer is positioned in the exit pupil and the observer views the projection unit at a predefined angle of observation. Each volume grating of the projection unit has a deflection efficiency curve dependent on the angle of observation with a maximal for the predefined angle of observation. The deflection efficiency curves are set equal for a predefined angle range around the predefined angle of observation by virtue of the fact that, for each of the volume gratings applied by exposure, the number of interference maxima applied by exposure is the same and the refractive index modulation for the corresponding wavelength, which refractive index modulation is applied by exposure, is the same.
