  • Patent number: 5327286
    Abstract: An optical correlation unit for correlating the images of an inspection object and a reference object. The unit uses two phase modulating reflective spatial light modulators. A first spatial light modulator receives electronic input in the form of image data representing the inspection object. It modulates incoming light with this input and reflects the modulated output to a first Fourier transform lens. This lens provides the optical input to a second spatial light modulator, whose electronic input is transform data representing the complex conjugate of the Fourier transform of the reference image. The electronic input modulates the optical input, resulting in the Fourier product of the two images, which is then transformed to provide correlation data.
