Abstract
A dual-modulation laser projection system () includes a polarizing beamsplitter () for splitting laser light () into first () and second () polarized beams having mutually orthogonal polarizations, a phase spatial light modulator () for beam steering the second polarized beam (), a mechanical amplitude spatial light modulator () for amplitude modulating a combination of the first polarized beam () and the second polarized beam () as beam steered by the phase spatial light modulator (), and a filter () for removing, from the combination () of the first and second polarized beams, one or more of a plurality of diffraction orders introduced by the mechanical amplitude spatial light modulator (), to generate filtered, modulated output light ().
