Abstract
A display system includes a coherent light source that can emit a coherent light beam, an optical component that can direct the coherent light beam to a spatial light modulator, a transport mechanism that can move the optical component to produce a movement in the coherent light beam, and a spatial light modulator having a two-dimensional array of mirrors each configured to selectively reflect the coherent light beam either toward a screen surface or away from the screen surface to form a display pixel on the screen surface. A display image is formed on the display screen by display pixels produced by the mirrors that reflect the coherent light beam toward the screen surface.
