ABSTRACT:
An optical system for directing light to a spatial light modulator 16 (e.g., a digital micro-mirror device) is disclosed herein. This system can be used with displays, printers or cameras. The system includes a first light generating apparatus 30a for generating a first beam of light and a second light generating apparatus 30b for generating a second beam of light. A first lens 36a directs the first beam of light toward the spatial light modulator 16 at a first angle. Also, a second lens 36b directs the second beam toward the spatial light modulator 16 at a second angle. The system also includes an apparatus 34 which redirects either the first or the second beam of light away from the spatial light modulator 16.
