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)
