A coherent optical apparatus of this invention includes first and second lenses located before and after a transmission object in which at least one of a transmittivity or phase is spatially distributed, and a microlens array located before the first lens. Upon illumination of coherent light on the microlens array, a plurality of high-quality, clear Fourier transform patterns can be obtained with a simple arrangement.
