Abstract

Vector tensor theory results have been applied to optimization of selfdiffraction phenomena in photorefractive crystals of symmetry 23. The giant diffraction efficiency of 77% in doped and radiate BTO crystal is observed. The signal to noise ratio was 600. Optimization algorithm for improving this ratio is proposed. These results are applied to small size sensors for some engineering applications.
