Beschreibung
Zusammenfassung:	An laser based image projection system for displaying images, which comprises an LCD device and projection optics. By introducing a diffuser between the LCD device and the projection optics, the quality of the projected image is improved. The visibility of material imperfections in the optical the beam path, which were previously visible in the projected image due to the large field-of-depth of the system, is now reduced.
