Abstract:

The use of photorefractive Bi12SiO20 BSO as a dynamic holographic medium in optical processing systems has been the subject of much activity. Typical operations carried out include edge enhancement, novelty filtering and the correlation of optical signals. However the use of BSO in coherent correlator systems is hindered by positional problems as the crystal -must be inserted at the Fourier plane of the transforming lenses to a high degree of accuracy to within 0.5 of the focal length of the lens as determined in ref 3.
