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.

Concealed grating structures

Light-emitting devices for motor vehicles are provided, which comprise a reflection hologram. A light-guiding body is provided to direct light from a light source arrangement () onto the hologram.

Illumination device for vehicles

Methods and apparatuses for mounting a material () on a carrier () are provided. To this end, the material is arranged on a porous layer () of an air bearing arrangement ().

Method and device for applying a material to a support

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.

Functionalized waveguide for a detector system

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.

Screen comprising a transparent base body

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.

A hologram for an illumination device for vehicles and a corresponding illumination device are provided. The hologram has a plurality of holographic structures designed for a respectively associated wavelength, wherein the holographic structures have diffraction properties that are identical among one another.

Light-emitting devices for motor vehicles are provided, which comprise a reflection hologram. A light-guiding body is provided to direct light from a light source arrangement onto the hologram.
