Achievements include 7 national patents for inventions in optical engineering.

Principle results of the investigation

• Prediction, observation and analysis of multiple Bragg acousto-optic interaction with a simultaneous existence of two, three and seven diffraction orders additionally to zero diffraction maximum (1973-1989). Examination of regular trends of light diffraction by ultrasond in case of double-frequency acoustic driving signal (1988).

• Experimental observation in media with induced optical anisotropy of Raman-Nath and intermediate between Bragg and Raman-Nath regimes of anisotropic light diffraction by acoustic waves (1980).

• Design and development of the first Russian tunable acousto-optic filter with a non-collinear geometry of light and hypersound interaction taking place in lithium niobate single crystal (1974). Realisation of electronic as well as of mechanic tuning of the filter over wide range of optical frequencies (1975). Design and development of acousto-optic cells of modulators and filters providing principle possibility of operation with arbitrary polarized monochromatic and non-monochromatic optical radiation (1986).

• Experimantal confirmation of the possibility of filtrate non-collimated optical rays and beams forming optical images in visible light, near and middle infrared regions of spectrum (1983-1989). Development of the tunable acousto-optical filter with the extremely wide angular optical aperture up to $52^{\circ }$ (1989). Confirmation of the possibility of spectral-polarization analysis of optical rays in visible and infrared regions of spectrum by means of a single acousto-optic cell (1991).

• Development of filters of spatial frequencies for processing of optical images of coherent light (1986-1988). Invention of acousto-optical tunable filter providing effective selection of spatial frequencies along two orthogonal directions simultaneously (1988).

• Prediction and observation of quasi-collinear regime of acousto-optical diffracrion of light by acoustic waves propagating in optically and acoustically anisotropic media (1990). Observation of the quasi-collinear regime of diffraction in the efficient acousto-optic material tellurium dioxide (1991). Realisation of the possibility to control electronically spectral transmission bandwidth of acousto-optic filter on base of paratellurite(1993). Observation electro-optic tuning of Bragg phase-matching frequency in the filter (1996)
