Abstract : A gas cell phase shifter was assembled and is undergoing preliminary tests. For the purpose of calibrating the phase shifter, a photomultiplier fringe detection system was adapted to a Twyman-Green interferometer. Initial work has begun on the differential phase shift interferometer. (Author)
