Abstract

We study practical opportunities of characterizing the angular or frequency bandwidth as well as the number of resolvable elements (spots) within a two-phonon light scattering in optically and acoustically anisotropic tellurium dioxide crystal when the efficiency of acousto-optical interaction is small enough to consider these problems in the first-order approximation. Then, an approach based on the transfer function technique is applied to estimating the angular bandwidth inherent in acousto-optical cell operating in a two-phonon light scattering regime. The obtained result is compared with the data related to a one-phonon regime of light scattering in isotropic medium. Finally, the number of resolvable elements is estimated for a two-phonon light scattering regime. In so doing, the combined diagram illustrating joint effect of a triplet of such factors as the geometric limitations and the acoustic attenuation, which restrict the number of spots just in the regime under consideration, has been created for the first time.
