The paper oonsiders the possibility of usin aoousto-optic thvioe or compensation o interatellar diepereion influonoe in observations o radio emission from pulsars. The principle of operation of an adaptive acousto-optical processor using COD-line photodetector in the shift-and-add mode is discussed. An adaption is the zensitivity of the receiver either by increasing the time of observations or by compensation of the dispersion effect, which permits to operate on the wide frequency band. 382
