DEVICE FOR CALIBRATION OF SEISMOACOUSTIC TRANSDUCERS Russian patent published in 2016 - IPC G01N29/04 G01N29/30 G01M7/02 G01H9/00 

FIELD: geophysics.

SUBSTANCE: invention relates to geophysical, particularly seismoacoustic, devices and can be used for control of characteristics of converters used in monitoring various technical objects. Device comprises radiating element, monolithic unit, a laser, a photodetector, a generator, a recording device and calibrated seismic-acoustic converter. Hole is made in monolithic block. Calibrated seismic-acoustic converter is installed on monolithic block of centre of its working surface on hole. At centre of working surface of calibrated seismic-acoustic converter is fixed mirror. Radiating element is used with a hole and is fixed at bottom of monolithic block. Holes of monolithic block and radiating element are arranged concentrically. Receiving unit is located in hole without touching mirror, and its output is connected with help of optical fibre with an optical splitter, a photodetector, a laser. Recording devices are connected to output of calibrated seismic-acoustic transducer and photodetector.

EFFECT: higher reliability and simple design.
