Paper Abstract

We present a holographic interferometer using a photorefractive crystal SBN:60. A point source is recorded inside the crystal via two wave-mixing. By displacing the crystal laterally or radially a tunable Young''s interferometer or a tunable Michelson interferometer is constructed respectively. An advantage of this device is the elimination of errors due to hologram developing and repositioning processes. The interferometer is capable of producing sinusoidal gratings and zone plates. 1.
