OPTICAL SEISMOACOUSTIC TRANSDUCER FOR MONITORING DESTRUCTION OF ROCK SAMPLES Russian patent published in 2024 - IPC G01V1/16 

FIELD: geophysics.

SUBSTANCE: invention relates to geophysics, in particular to investigations of destruction of rock samples when load changes, and can be used to obtain predictive characteristics of control of cracking in rock mass. In the optical seismoacoustic transducer for monitoring the destruction of rock samples, a second electrical connector, an optical splitter, an optical emitter are additionally installed in the cover, optical emitter control electronic circuit, photodetector electronic matching circuit, wherein the first input of the optical splitter is connected to the output of the optical emitter, the input of the optical emitter is connected through the electronic control circuit of the optical emitter to the second electrical connector, the second input of the optical splitter is connected through the optical fibre to the head of the fibre-optic interferometer, the first output of the optical splitter is connected to the photodetector, wherein the output of the photodetector through the electronic matching circuit of the photodetector is connected to an electrical connector placed on the cover of the housing, the second output of the optical splitter is connected to the optical fibre of the fibre-optic interferometer.

EFFECT: high reliability of measurements and reliability of adjustment.
