THREE-COMPONENT WELL SEISMOGRAPH Russian patent published in 2015 - IPC G01V1/16 

FIELD: instrumentation.

SUBSTANCE: as inert mass the assembly out of three orthogonal lasers is used, it is installed on the cable secured on the spring suspension. On the internal surface of the casing there are three mutually orthogonal LCCD-matrices. At that in quiescent state the laser beams are oriented as per the centres of the LCCD-matrices, and distances from the lasers to the LCCD-matrices are same. Cable does not contact with the casing and is used to hold the orthogonal lasers assembly, for power supply to them, and for their orientation as per cardinal directions.

EFFECT: increased accuracy of oscillations registration.
