Title:
光回折素子、及び、光演算システム
Document Type and Number:
Japanese Patent JP7426474
Kind Code:
B2
Abstract:
Provided is a light diffraction element which can output signal light indicative of information before the computing, in addition to signal light indicative of information after the computing. A light diffraction element (1) is constituted by a plurality of cells. In the cells of the light diffraction element (1), first regions (C1) allow first polarized components (X polarized components) to pass through and have respective thicknesses or refractive indices that are independently set; and second regions (C2) allow second polarized components (Y polarized components) to pass through and have uniform thicknesses or uniform refractive indices, the second polarized components being different in polarization direction from the first polarized components.
