Abstract:
A system and method for reducing visible speckle in images displayed using coherent light. In an embodiment, a system for displaying images includes a light source to produce coherent light, an array of light modulators optically coupled to the light source and positioned in a light path of the light source after the light source, and a controller electronically coupled to the array of light modulators and to the light source. The light source includes a coherent light source, and a first digital micromirror device (DMD) having a first plurality of micromirrors. The first DMD is optically coupled to the coherent light source and positioned in a light path of the coherent light source after the coherent light source. The first DMD directs coherent light by moving the micromirrors of the first plurality of micromirrors through a first range of tilt angles substantially continuously.
