Abstract
The method of studying of dynamic diffraction gratings formed in acousto-optic devices is presented. Using a receiving scanning acoustic microscope, acousto-optic modulators of the same shape made of quartz glass and crystalline quartz were studied. Grating shape blurring effects and appearing of spurious gratings due to wave re-reflection were observed. It is shown that the grating structure demonstrates high correspondence to the theoretical shape in quartz glass whereas differences associated with material anisotropy are visible in crystalline quartz. The connection between the structure of dynamic gratings and characteristics of acousto-optic devices is discussed.
