Abstract
A liquid crystal spatial light modulator for adjusting an optical signal is configured in such a manner that a region of one element is partitioned into two regions so as to perform intensity modulation in one region and phase modulation in the other region. Since the region for performing the intensity modulation and the region for performing the phase modulation can be formed by partitioning one region of the liquid crystal spatial light modulator, only one element allows adjusting functions, both the optical signal intensity modulation and phase modulation.
