Abstract
A 3D projector having two light modulators for modulating light from a single broadband light source, without loss of light being dumped into heat. In embodiments, light splitters (e.g. dichroic) are used to split one wavelength combination to one light modulator, and the other wavelength combination to the other light modulator, such that discarded spectrum from one modulator is used to illuminate the other modulator.
