Paper Abstract

Phase difference amplification is a technique to produce a contour map of an object in which the optical path difference corresponding to one fringe equals a small fraction of the wavelength of light. In this paper we report a method for phase difference amplification using multiple beam interference in conjunction with an optically addressed liquid crystal spatial light modulator. This interferometer operates in near real time and is ten times more sensitive than a conventional interferometer.
