An adder unit ( 60 e) reads a desired CGH pattern from a pattern memory unit ( 60 a) and a phase distortion correction pattern from a distortion-correction pattern memory unit ( 60 d) and adds both patterns together to generate a phase distortion corrected pattern. A control unit ( 60 g) controls a phase modulation module ( 40 ) in accordance with the phase distortion corrected pattern. Accordingly, phase-modulated light based on the desired phase pattern can be generated precisely, easily and quickly. |
