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.
Claims24
An optical system comprising:
- a first light source;
- a second light source;
- and
- a spatial light modulator;
- wherein the first light source has a first optical output that is processed by a first part of the spatial light modulator and the second light source has a second optical output that is processed by a second part of the spatial light modulator.
