  • Wave front sensor
    Patent number: 4490039
    Abstract: An improved wave front sensor for analyzing, measuring and controlling optical wave fronts incorporates detectors having a large number of photosensitive elements smaller than the beam spot size so that source and reference beam spot centers may be more accurately located and greater alignment errors may be tolerated. A reference beam may be switched on intermittently, thereby improving signal-to-noise ratio.
