Paper Abstract

A plate shearing interferometer can be used for measurement of the optical aspherical surfaces. Being common path this kind of interferometer is quite stable. The use of a plate shearing interferometer for fringe scanning interferometry is discussed. The phase shifting is provided by a new technique presented in this paper. It is shown theoretically and experimentally that this technique can be used for real time wavefront-aberration detection with greater pricision.
