Paper Abstract

An approximate solution of the equations governing collinear acousto-optical interaction in terms of confluent hyper- geometric function is obtained under conditions of plane- wave approximation. However, the experimental acousto- optical devices deal with a beam of finite dimensions which imply a substantial transversal and longitudinal inhomogeneity altering considerably the results of diffraction. A theory of such quasi-collinear interaction is suggested. An acousto-optical tunable filter is one of most promising devices using acousto-optical diffraction and able to ensure high-resolution spectral analysis of natural optical radiations could further be improved if two instead of one consequently arranged crystals were used in the acousto-optical cell.
