System for projecting or displaying images

摘要

The invention relates to a system for projecting or displaying images comprising a valve exhibiting a plurality of image-forming elements having a light transmission coefficient which can be controlled so as to present the image, and a means of illuminating the valve comprising a light source and an integrator having two lens arrays associated in such a way that each lens of the second array distributes over the valve the light received from a corresponding lens of the first array. This system comprises a means for focusing the illuminating beam onto the integrator. The dimensions of the integrator are thus minimized. The focusing means comprises, for example, a reflector which reflects the light produced by the source, the integrator being arranged substantially in the focal plane of the reflector.
