  • Patent number: 5877803
    Abstract: A three dimensional image detector is disclosed. The three dimensional image detector has a lensing system to focus incident light reflected from an object field upon a first and second image detector. The first and second image detectors are matrices of charge coupled devices. The first and second image detectors convert the incident light to electrical signals. The electrical signals from the first and second image detectors are converted in an analog to digital converter to a plurality of digital words that represent the magnitude of the light that impinges upon the first and second image detectors. The plurality of digital words are retained in a random access memory for processing within a digital signal processor. The digital signal processor will locate an object within the object field and determine the depth and contour information of the object and present this information with the plurality of digital words to external circuitry for further processing or display.
