Title:
二重変調レーザ投影システム及び方法
Document Type and Number:
Japanese Patent JP7387753
Kind Code:
B2
Abstract:
A dual-modulation laser projection system (100) includes a polarizing beamsplitter (110) for splitting laser light (180) into first (182) and second (184) polarized beams having mutually orthogonal polarizations, a phase spatial light modulator (120) for beam steering the second polarized beam (184), a mechanical amplitude spatial light modulator (130) for amplitude modulating a combination of the first polarized beam (182) and the second polarized beam (186) as beam steered by the phase spatial light modulator (120), and a filter (140) for removing, from the combination (190) of the first and second polarized beams, one or more of a plurality of diffraction orders introduced by the mechanical amplitude spatial light modulator (130), to generate filtered, modulated output light (192).
