Аннотация

The possibility of formation of a 2D optical image contour during double Bragg’s diffraction simultaneously in two Bragg’s orders is investigated. Transfer functions of Bragg’s orders of double diffraction are obtained with account for ellipticity of optical beams and the curvature of wave surfaces of the crystal. The conditions for obtaining the image contour simultaneously in the zeroth and plus second Bragg’s orders are determined. This is confirmed experimentally using the example of Fourier processing of the image transferred by radiation at a wavelength of 0.63 μm. Double Bragg’s diffraction is realized based on an acousto-optic cell made of a uniaxial gyrotropic paratellurite crystal, which operates at an acoustic frequency of 20.3 MHz.
