PCT No. PCT/US83/00184 Sec. 371 Date Sep. 23, 1983 Sec. 102(e) Date Oct. 12, 1983 PCT Filed Feb. 14, 1983 PCT Pub. No. WO83/02831 PCT Pub. Date Aug. 18, 1983.A method and apparatus for performing optical processing on optical information corresponding to a subject (66) combines known optical processing techniques with holography. A reverse ray-trace holographic system is provided so that the image reconstruction beam (90) passes through the optical system in a direction exactly opposite to that travelled by the subject beam (50) during recording of the hologram (88). Aberrations introduced by the system optics are then completely compensated for, allowing use of lower quality optical components. A single large-aperture lens (68) is used to define a Fourier transform of the optical subject information as the hologram (88) is recorded or the image reconstructed, and the subject information is manipulated within the Fourier transform plane (91).
