Abstract
A light control deviceincludes 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 modulatoris a phase modulating spatial light modulator, includes a plurality of two-dimensionally arrayed pixels, is capable of phase modulation in each of these pixels in a range of 4π or more, 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 light diffraction and a phase pattern having a predetermined phase modulation distribution, and with a phase modulation range of 2π or more.
