Multichannel spatial light modulator

摘要

Design and principles of the multichannel modulator of light created on the basis of photorefractive crystals Bi_12GeO_20, Bi_12SiO_20 are resulted in the work. The high gear characteristics of the modulator are acheived at use of a design of male electrodes. The calculation of distribution of electricla fields and induced difference of phases is conducted depending on a structure of male electrodes and thickness of a crystal plane. The modulation and temporary characteristics of the multichannel modulator of light experimentally are investigated.
