Abstract

See full text

Described examples include a projector including a first prism having a dichroic layer. A second prism has a first spatial light modulator on a first surface, and a first light source directed through a second surface of the second prism to the first spatial light modulator. The first spatial light modulator is operable to modulate the first light to provide modulated first light that is reflected off the second surface of the second prism and the dichroic layer to projection optics. A third prism has a second spatial light modulator on a first surface and a second light source directed through a second surface to the second spatial light modulator. The second spatial light modulator is operable to modulate the second light to provide modulated second light that is reflected off the second surface of the third prism and passes through the dichroic layer to the projection optics.
