摘要：
A digital image projector for increasing brightness includes a first light source; a second light source that is spectrally adjacent to the first light source; a dichroic beamsplitter disposed to direct light of both the first and second light source; a spatial light modulator that receives light from both the first and second light sources; and projection optics for delivering imaging light from the spatial light modulator.
