Patent ID: 7938547

Claim:
A display system, comprising: a coherent light source configured to emit a coherent light beam; a first optical component configured to split the coherent light beam into a first sub-beam and a second sub-beam; a second optical component configured to combine the first sub-beam and the second sub-beam to form a recombined coherent light beam to be directed to a spatial light modulator; a third optical component configured to direct the second sub-beam from the first optical component to the second optical component; a transport mechanism configured to move the third optical component to produce a movement in the second sub-beam; and a spatial light modulator having a two-dimensional array of mirrors each configured to selectively reflect the recombined coherent light beam either toward a screen surface or away from the screen surface to form a display pixel on the screen surface, wherein a display image is formed on the screen surface by display pixels produced by the mirrors that reflect the recombined coherent light beam toward the screen surface.
