Abstract

A simple image subtraction technique with photorefractive real- time holographic interferometry is analyzed and experimentally demonstrated, where the (pi) phase difference between the two images to be subtracted is automatically introduced by the phase shift of reconstructed wave from the incident wave in two wave coupling process. Its performance and requirements for a good result are discussed.
