Abstract

The development of a holographic image processing computer has resulted in an exceptional quality display of both time average and real-time holographic interference patterns. The same processor, however, can be used for shearography, speckle correlation interferometry, and moire interferometry. This paper describes the various modules that have been developed for converting the standard electronic holography optical head into any of the other three modes of operation. The advantages of using a holographic image processing computer for these alternate forms of interferometry will be outlined.
