Abstract

Global and local surface-fitting algorithms for interferogram reduction have been programmed at White Sands Missile Range. A program has also been written which uses a combination of Zernike polynomial fitting and local quadratic surface fitting for interpolation. A comparison of results from the methods programmed is given.
