Abstract:
An objective of the present invention is to carry out a correction for the influence of disclination in a phase modulation element, thereby improving the precision of the phase modulation. This information processing device is provided with an adjustment unit for shifting a phase distribution range (B2) of light that has passed through the phase modulation element with respect to a possible phase modulation range (A1) of a phase modulation element, so as to reduce the difference between a center value of the possible phase modulation range and an average value of the phase distribution range.
