There is represented an information about phase inverters with split load. It is noted the problem of provision of identity of different polar signals at split loads. There are mentioned the specificities of Bragg’s diffraction in context of shaping of two different polar signals. It is shown that in case of modification of the frequency of electric signal at the input of acousto-optic modulator the diffraction order shifts in the plane which is perpendicular to the optical axis. It is represented the structural circuit of acousto-optic phase inverter with split load. For generation of two different polar signals the deflected beam is divided into two beams biased in the same direction. Slits in the screens are placed correspondingly at the left and at the right halves of the shaped beams. It is researched the theoretic aspects of generation of different polar signals which are used for numerical analysis of the proposed circuit functionality. The results of the theoretic researches are proved experimentally. It is represented the circuit of the experimental set. Experimental sample of the phase inverter is made using acousto-optical modulator fabricated from glassy photo elastic material of TF-7 type. Laboratory sample of photo receiving device is used for experimental researches. There are represented the results of experimental researches and it is shown their identical match the theoretic researches results.
