Abstract
A method includes inputting, via a first position adjustment optical structure, adjustment signal light into a second position adjustment optical structure. A first light diffraction element of an optical computing device includes a first computing optical structure constituted by microcells, and the first position adjustment optical structure. A second light diffraction element of the optical computing device includes a second computing optical structure constituted by microcells, and the second position adjustment optical structure. The method includes adjusting, based on the adjustment signal light outputted from the second position adjustment optical structure, a position of the second light diffraction element with respect to the first light diffraction element.
