Moire interferometry is a technique for the measurement of small displacements using the interference pattern produced by two gratings. One of the gratings must be attached to the surface of the specimen where the measurements are to be taken. A process recently developed produces a grating on the surface of a photographic plate which is then replicated onto the surface of the specimen, a process which destroys the grating on the photographic plate. It is the purpose of this thesis to present a method by which the grating on the photographic plate is replicated, not onto the specimen, but first onto a glass plate, from which many more replicas can be made.
