Abstract
The paper presents results on theoretical and experimental investigation of tunable acousto-optic filters and their applications in optics and spectroscopy for spectral filtration of divergent optical beams and images. Physical principles of operation of wide-angular acousto-optic filters are examined and basic parameters of developed instruments are described in the paper. The instruments intended for processing of optical images are designed on base of optically anisotropic single crystals of tellurium dioxide. Various experimental block-schemes and optical arrangements for image processing are described and some peculiarities of the imaging experiments are presented in the paper. In particular, experimental results on acousto- optic imaging by means of tunable filters not sensitive to polarization of incident optical radiation are examined and processing of infrared images characterized by relatively low intensity of light beams is described in the report. Proposals on design of acousto-optic cells optimized for the imaging experiments are also presented and discussed in the paper.
