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 ultrasound 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
  monochromatic
  and non-monochromatic optical radiation (1986).
• Experimental 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 ${\displaystyle 52^{\circ }}$ (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 diffraction 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)^[15]
• Prediction and observation of unknown regimes of Raman-Nath diffraction of light by ultrasound propagating in media with strong acoustic anisotropy (1997). Experimental observation of unusual propagation and reflection of acoustic wave in anisotropic crystals (1998).
