Patent Number Title Of Patent Date Issued
4566757 Holographic optical processing method and apparatus January 28, 1986
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 t
4516833 Production of high performance optical spatial filters May 14, 1985
High performance optical spatial filters are produced photographically with an apparatus that directs a coherent beam of light through or off a subject and into a lens. The lens focuses the diffracted and/or reflected light to define a Fourier transform of the subject information. A filt
4478481 Production of diffraction limited holographic images October 23, 1984
An apparatus for the production of a holographic image of a subject disposed at a subject plane includes a source of coherent light divided by a beamsplitter into a reference beam and a subject beam. The subject beam is directed towards the subject through a beamsplitter and a quarter-wa
