GRAVITATION-WAVE DETECTOR Russian patent published in 2007 - IPC G01V7/00 

FIELD: laser-interferometer gravitation-wave detectors, possible use for detecting low frequency periodic gravitation-wave signals from double relativistic astrophysical objects.

SUBSTANCE: introduced into each resonator of two-resonator laser system with common active environment and geometrically non-equivalent contours are: first and second correctors of optical length, first and second piezo-elements of reverse effect, first and second amplifiers, first and second piezo-elements of direct effect. These elements, interconnected appropriately, ensure mutual evening of geometrical lengths of first and second resonators, resulting in compensation of temperature fluctuations of difference of phases of optical beam flows.

EFFECT: ensured reduction of non-correlated low frequency phase noises in optical radiations.
