Abstract
FIELD: laser measurement technology; geophysics for recording strain displacement of earth's crust. SUBSTANCE: system that has known components is provided with phase detector, high-voltage amplifier, and additional piezoid; two inputs of phase detector are connected to respective outputs of second and third photodetectors and its output is connected to input of high-voltage amplifier whose output is connected to additional piezoid coupled with first laser light source. EFFECT: provision for generating direct displacement signal; simplified recording system, improved reliability and reduced cost. 2 cl, 2 dwg
