Optical computation system

Abstract

An optical computing system includes: an intensity modulation device group including at least two intensity modulation devices, each of which includes modulation cells, wherein each of the modulation cells of each of the intensity modulation devices carries out intensity modulation with respect to carrier light in accordance with one of signals to generate a signal light beam, and each of the signals corresponds to each of the intensity modulation devices; and a light diffraction element including diffraction cells having respective thicknesses or refractive indices set independently of each other, wherein each of the diffraction cells receives the signal light beam from each of the modulation cells of each of the intensity modulation devices corresponding to each of the diffraction cells, and by causing signal light beams to have respective different optical path lengths to the light diffraction element, the signal light beams have respective different phases.
