Reduced Rainbow Artifacts in Digital Light Projection Systems

摘要

A projection system can include a color wheel and at least one digital micromirror device. The color wheel can produce different colors of light from a light source. Each color can be produced in sequential order for a predetermined color phase. Each of the digital micromirror device(s) can have a plurality of micromirrors. At least one of the plurality of micromirrors can be activated at different respective portions of each of two consecutive color phases responsive to a control signal. The projection system also can include a lens configured to project light reflected from the at least one digital micromirror device onto a projection surface.
