摘要：A light control device 1 includes a light source 10, a prism 20, a spatial lightmodulator 30, a drive unit 31, a control unit 32, a lens 41, an aperture 42, and a lens 43.The spatial light modulator 30 is a phase modulating spatial light modulator, includes aplurality of two-dimensionally arrayed pixels, is capable of phase modulation in each ofthese pixels in a range of 4π or more, and presents a phase pattern to modulate thephase of light in each of the pixels. This phase pattern is produced by superimposing ablazed grating pattern for light diffraction and a phase pattern having a predeterminedphase modulation distribution, and with a phase modulation range of 2π or more.
