Abstract:
An optical system and method that utilize multiple low-etendue lasers to illuminate multiple spots one or more spatial light modulators. Stereoscopic systems may be formed by using different wavelengths or different polarizations for each spot. Light from each spot is guided to each eye of the viewer by wearing 3D glasses.
