COHERENT OPTICAL SURVEILLANCE DEVICES
Abstract
Research concerned the development of coherent optical components operative over the spectral range from 0.5 to 0.8 microns. Design considerations were made and designs finalized for a gas cell variable phase shifter to provide 180 degrees phase shift of light at 7000 angstroms with a sensitivity of better than 1 degree. A study of the relative merits of double beam and multiple beam methods of calibrating the phase shifter using incoherent light was made. A survey of photomultiplier tubes was made to select that tube which will be most useful for calibration and evaluation purposes. (Author)
