  • Space integrating ambiguity processor
    Patent number: 4440472
    Abstract: A space integrating optical ambiguity processor in which two one-dimensional modulators provide two-dimensional processing capability. Signals to be processed drive orthogonal Bragg cells oriented 40.degree. to the axes of the output detector. The resulting product is transformed in one dimension and imaged in the other, thereby creating a light intensity distribution representative of the cross ambiguity between the input signals.
