(under the class definition) Subject matter wherein basic and more involved mathematical processes of comparing, adding, substracting, multiplying, dividing, integrating, etc., are perfomed by optical elements on an optical beam prior to any conversion to another form of energy.
(1) Note. The optical beam itself performs the computing.
(2) Note. The computing of this and the indented subclass optically works on a single input optical beam to produce a desired output optical beam, but this optical computing is not intended to encompass convolution (crosscorrela-tion) or correlation functions performed by a diffration grating.
(3) Note. Electrical computing for optical purposes without
any computation using an optical beam are not classified in this subclass (See Search Class for Class 364, subclass 200).
