Abstract
An optical computing device includes a light diffraction element group including light diffraction elements each having an optical computing function, and a light receiver that detects respective intensities of wavelength components contained in signal light outputted from the light diffraction element group. The light diffraction elements are disposed side by side on a light path of the signal light inputted into the light diffraction element group such that the signal light passes sequentially through the light diffraction elements.
