An automated electro-optical comparator system Available to Purchase

A high speed automated Electro-Optical Comparator (EOC) system is described. The EOC utilizes a servo driven air bearing transport to move a 2,048 element CCD camera over a two dimensional pattern. High speed processing of the camera signals, in combination with computer comparisons of the sensed pattern and the previously stored ideal pattern provides near real time measures of the deviation of the sensed pattern from the ideal pattern.
