Laser projection arrangement and process for the generation of virtual images

Abstract

The Disclosure concerns a laser projection arrangement and a process for the generation of virtual images, the purpose of which is to present a solution which allows a representation of multiple virtual images in different distances or planes and different points of view and that can be manufactured economically. On the arrangement side, this purpose is solved when one of at least two picture generating units that generate virtual images that differ in their wavelength and/or their polarization is arranged and when a holographic optical element is arranged on or in the projection surface. On the process side, the purpose is solved when two virtual images with different wavelengths and/or different polarizations are generated, when a holographic optical element is provided which exhibits different optical properties for different wavelengths and/or different polarizations, and when, in the case of projection of the virtual images while making use of the holographic optical element, the virtual images are represented, due to the different optical properties, at different distances from the driver and/or in different points of view from the driver.
