Аннотация:A detailed analysis of the acousto-optical effect in biaxial crystals is performed using the examples of thallium tetratioarsenate (Tl3AsS4) and iodic acid (α-HIO3) crystals of rhombic syngony. The optimum cross sections of the crystals are determined for such acousto-optical devices as deflectors and filters. Theprospects for using thallium tetratioarsenate crystal to create high-performance acousto-optical deflectors and quasi-collinear filters in the near- and mid-IR ranges are demonstrated. It is established that the spectral resolution of acousto-optical filters based on this variant of diffraction is comparable to the resolution of quasi-collinear filters with the same length of acousto-optical interaction.
