Paper Abstract

Electrooptic and photoconductive Bismuth Silicon Oxyde (B.S.O.) crystals allows the recording of phase volume holograms through the photorefractive effect. We demonstrate applications to real time non destructive testing using holographic interferometry by double-exposure, time average and speckle technics. We also report in this paper, the possibility of using optical fibers for object and reference wavefronts generation. In fine, we show that it is possible to induce energy transfert between reference and object beams. Application to image amplification and mode pattern visualisation of 3-D diffuse object are demonstrated.
