Paper Abstract

The present work demonstrates the use of a general purpose interferometer to measure the deformations of a scattering surface by processing speckle patterns instead of smooth wavefronts. The operation of the interferometer are re- programmed to include algorithms adapted to handling speckle patterns. Details of the measuring operation are described, limits of applicability are discussed, and experimental results are presented.
