Abstract
The work explores the possibility of using the acousto-optical effect to demodulate a sequence of radio pulses. Measuring setup circuits for determining sequence parameters are proposed. The methods for analyzing the diffraction pattern that relate the intensity distribution to the signal characteristics are described. Experimental and theoretical curves are constructed. Based on the data obtained, a conclusion is made regarding the requirements for the materials of crystals which is the main part of acousto-optic cells. The conditions for the appearance of uncertainty regions are described.
