Abstract:
1. A projection system, comprising: a light source for generating and emitting light; first, second, third and fourth sets of digital micromirror device imagers, each of the sets having first, second, and third digital micromirror device imagers, the first, second, and third digital micromirror device imagers each being configured to receive and reflect incident light of a different color;. an initial beam splitter for splitting the light from the light source into a first intermediate beam and a second intermediate beam; a first beam splitter for splitting the first intermediate beam into a first beam and second beam; a second beam splitter for splitting the second intermediate beam into a third beam and fourth beam; first, second, third and fourth dichroic prisms for receiving the first, second, third and fourth beams, respectively, each of the prisms splitting the respective beams into the incident light of three different colors; and a projection optics system for receiving and projecting reflected light of the three different colors from each of the sets of digital micromirror device imagers, the projection optics system being configured to direct the reflected light from each of the sets of digital micromirror device imagers to a different portion of a display surface.
