摘要：A light control device includes a light source , a prism , a spatial light modulator, a drive unit , a control unit , a lens , an aperture , and a lens . The spatial light modulator
is a phase modulating spatial light modulator, includes a plurality of two-dimensionallyarrayed pixels, is capable of phase modulation in each of these pixels in a range of 4π ormore, and presents a phase pattern to modulate the phase of light in each of the pixels.This phase pattern is produced by superimposing a blazed grating pattern for lightdiffraction and a phase pattern having a predetermined phase modulation distribution,and with a phase modulation range of 2π or more.
