FIELD: measuring equipment.
SUBSTANCE: acousto-optical device for measuring parameters of radio signals includes successively light arranged laser, collimator, AO deflector on electrical input of which is measured radio signal, an integrating lens in focal plane of which there is a recording device, and a cylindrical lens arranged between integrating lens and linear photodetectors. On path of diffracted beams between deflector and integrating lens prism is placed from translucent homogeneous material with normal dispersion. Base of prism parallel to plane of AO interaction, and angle of incidence of diffracted beams on inlet face of prism and refracting angle are maximum possible, provided no on output face of prism total internal reflection of light beams in entire operating frequency range AO meter.
EFFECT: technical result is high resolution of acousto-optical measuring parameters of radio signal.
