FIELD: acoustics.
SUBSTANCE: invention refers to acousto-optic training facilities and stimulators and can be used to study methods and means of acousto-optic compound radio signal processing. On device optical axis between second Bragg cell and object third and fourth Bragg cells are located immediately adjacent to one, another with identical acoustic wave propagation directions. Third and fourth Bragg cells are displaced from each other by value Δx=V·τ"И", where V is acoustic wave propagation velocity, and τ"И" is duration of signal elements. Piezoelectric transducers inputs of third and fourth Bragg cells are connected, through the fourth switch, to the first input of the third switch. Within propagation path of diffracted third and fourth Bragg cells of light beam segment there is the third lens provided with focal plane containing fourth photoconverter with output connected to the first input of the fourth oscillograph second input of which is connected to power supply output.
EFFECT: extended device functionality due to evident demonstration of synchronous detection of compound signals with binary phase manipulation.
