FIELD: physics.
SUBSTANCE: device includes a radiating element, the investigated seismoacoustic transducer, a reference mirror, an optical photodetector, a laser and an optical prism with a semitransparent mirror placed at an angle of 45° to the base. The prism is placed between the radiating element and the investigated seismoacoustic transducer. The radiating and control elements used are a piezoceramic ring with which the optical photodetector is arranged concentrically. The reference mirror and the optical photodetector are acoustically decoupled with the radiating element and the prism.
EFFECT: high sensitivity and simple design of the device.
