Laserprojektionssystem

摘要

A display apparatus (10), includes a laser light source (20) for emitting a light beam; a beam expander (24) for expanding the light beam; a spatial light modulator (52); beam shaping optics (38) for shaping the expanded laser beam to provide uniform illumination of the spatial light modulator (52), the beam shaping optics including a fly's eye integrator (40) having an array of lenslets; and a moving diffuser (34) located in the laser beam between the laser light source (20) and the spatial light modulator (52).
