Laser projection device having a diffuser arranged in an image focal plane and an object focal plane and method for manufacturing a laser projection device
Abstract:
Laser projection device comprising an image generating unit, intermediate imaging optics configured to generate an intermediate image at an image focal plane (210), an image diffusing element (300) and a projection lens (400) with an object focal plane (410), wherein the image diffusing element (300) is arranged in the image focal plane (210) and in the object focal plane (410) and comprises a superimposed microstructure (310) formed of constituent parts (311), which are regularly distributed within a surface plane (320) of the image diffusing element (300).
