摘要： 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.

摘要： An illumination apparatus for a motor vehicle comprises: a light source, an optical waveguide with an incident surface and a reflective region; and a hologram arranged on or in the optical waveguide. The illumination apparatus is configured such that light emitted by the light source enters the incident surface of the optical waveguide in the direction of the reflective region, is reflected by the reflective region inside the optical waveguide in the direction of the hologram and interacts with the hologram. The average distance between the light source and the incident surface is at least half as great as the average distance between the reflective region and the hologram.

摘要： A lighting device (31), in particular a rear luminaire, for a vehicle (30) is provided. The lighting device (31) has a hologram (34) and a light source (32) for illuminating the hologram (34). An image, more particularly a real image (35), is thereby generated, which can also lie outside the physical boundaries of the lighting device (31).

摘要： 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.

摘要： 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.
