Paper Abstract

Holographic interferometry is a nondestructive testing technique with a growing number of industrial applications. Photosensitive plates used for coherent wavefront recording generally require processing time, and it seems of particular interest to have new reusable materials allowing in situ interferogram writing and erasure with a recording energy comparable with high resolution photographic plates. We report in this conference a particular application of highly sensitive photoconductive cubic crystals Bi12 Si020 (BSO) to double-exposure real-time interferometry.
