US Patent:

51328135, Jul 21, 1992

Filed:

Dec 19, 1990

Appl. No.:

7/631104

Inventors:

H. John Caulfield - Huntsville AL
Charles F. Hester - Huntsville AL
Jason M. Kinser - Huntsville AL
Joseph Shamir - Huntsville AL

Assignee:

Teledyne Industries, Inc. - Los Angeles CA

International Classification:

G03H 112

US Classification:

359 11

Abstract:

An optical apparatus for simulating a highly interconnected neural network is disclosed as including a spatial light modulator (SLM), an inputting device, a laser, a detecting device, and a page-oriented holographic component. The inputting device applies input signals to the SLM. The holographic component optically interconnects N. sup. 2 pixels defined on the spatial light modulator to N. sup. 2 pixels defined on a detecting surface of the detecting device. The interconnections are made by N. sup. 2 patterns of up to N. sup. 2 interconnection weight encoded beams projected by N. sup. 2 planar, or essentially two-dimensional, holograms arranged in a spatially localized array within the holographic component. The SLM modulates the encoded beams and directs them onto the detecting surface wherein a parameter of the beams is evaluated at each pixel thereof. The evaluated parameter is transformed according to a nonlinear threshold function to provide transformed signals which can be fed back to the SLM for further iterations.

Abstract:

An optical apparatus for simulating a highly interconnected neural network is disclosed as including a spatial light modulator (SLM), an inputting device, a laser, a detecting device, and a page-oriented hologaphic component. The inputting device applies input signals to the SLM. The holographic component optically interconnects N. sup. 2 pixels defined on the spatial light modulator to N. sup. 2 pixels defined on a detecting surface of the detecting device. The interconnections are made by N. sup. 2 patterns of up to N. sup. 2 interconnection weight encoded beams projected by N. sup. 2 planar, or essentially two-dimensional, holograms arranged in a spatially localized array within the holographic component.
