Paper Abstract

Interferogram analysis is discussed as a sampling problem using the concepts of Fourier analysis. The relative merits of random, raster, and uniform sampling of a wavefront are examined. A relationship between a global least squares fit and interpolation in the spatial domain and transfer functions in the frequency domain is described.
