Abstract
A light diffraction element includes a computing optical structure constituted by microcells, and a position adjustment optical structure outside the computing optical structure.
Claims9
A light diffraction element comprising:
- a single substrate;
- a computing optical structure constituted by microcells;
- and
- a position adjustment optical structure disposed outside the computing optical structure, wherein
- the computing optical structure and the position adjustment optical structure are disposed on the single substrate.

An optical computing device comprising:
- a first light diffraction element comprising:
- a first computing optical structure constituted by microcells;
- and
- a first position adjustment optical structure disposed outside the first computing optical structure;
- and
- a second light diffraction element comprising:
- a second computing optical structure constituted by microcells;
- and
- a second position adjustment optical structure disposed outside the second computing optical structure, wherein
- the first position adjustment optical structure forms, on the second position adjustment optical structure, an optical image having an intensity distribution, and
- the second position adjustment optical structure changes, in accordance with a position of the second light diffraction element with respect to the first light diffraction element, the intensity distribution of the formed optical image.
