METHOD OF SEISMOACOUSTIC TRANSDUCERS CALIBRATION Russian patent published in 2017 - IPC G01V13/00 G01N29/30 

FIELD: measurement technology.

SUBSTANCE: invention relates to geophysical, particularly seismoacoustic, methods of studies, and can be used for seismoacoustic transducers characteristics calibration. According to present disclosure, monolithic block with two holes is used, installing two seismoacoustic transducers, standard and calibrated on monolithic block, directly determining reference and calibrated seismoacoustic transducers working surfaces offset separately through holes by interference linear displacements meter, represented by multi-beam optical interferometers. Used emitter is mosaic structure consisting of several piezoelectric elements. Each mosaic structure element is separately controlled by its signal from generator. Regulating each mosaic structure element radiation power obtaining identical offset values, and then performing calibration.

EFFECT: increasing in measurements reliability and excitation accuracy.
