ABSTRACT:
A method and apparatus for correcting errors in an optical measurement system utilizing a lens which may have distortions that would vary as a function of distance, by providing an encoded indication of the distortions of the lens for use by the system operator together with distance information to input a microprocessor and modify the signal from the detectors in the system to produce an accurate output.
