Abstract
The process of reading mixed transmission holograms formed in a photorefractive Bi12TiO20 piezoelectric crystal (sillenite family) of arbitrary cut has been theoretically optimized. The optimal crystal cuts, which provide the highest diffraction efficiency of holograms, are determined. The results of the theoretical analysis are based on the previously obtained experimental data; they are in agreement with the crystal point symmetry group and may serve as the basis for increasing the efficiency of dynamic holography devices with Bi12TiO20 crystals.
