    摘要： An optical computing device (1) includes an optical diffraction element group (11) and a filter (12) which is disposed so as to precede the optical diffraction element group (11). The optical diffraction element group (11) includes at least one optical diffraction element (11a1 to 11an) having an optical computing function. The filter (12) selectively transmits light which travels in a direction that forms an angle equal to or smaller than a specific angle (θ1) with an optical axis (L1) of a first optical diffraction element (11a1) which is included in the at least one optical diffraction element included in the optical diffraction element group (11) and which signal light first enters.
