Abstract
An optical computing system includes: a light diffraction element group including n pieces of light diffraction elements, where n is a natural number of 2 or more. Each of the n pieces includes cells, each of which has a thickness or a refractive index that is independently set. Each of the cells is classified into a C1 cell or a C2 cell. The thickness or the refractive index of each of the C1 cells is set such that optical computing that is carried out by the light diffraction element group becomes an identity operation when the C2 cells are masked.
