GRAVITATION-WAVE DETECTOR

摘要

FIELD: laser-interferometer gravitation-wave detectors, possible use for detection of low frequency periodic gravitation-wave signals from binary relativistic astrophysical objects. ^ SUBSTANCE: in accordance to the invention, into each resonator of two-resonator laser system with common active environment and geometrically equivalent contours, thermal compensators are introduced, with usage of piezo-elements for direct and reverse transformation, which ensure equality of optical paths of first and second resonators, which may be disrupted due to temperature changes. ^ EFFECT: ensured compensation of temperature fluctuations of difference of phases of optical streams, making it possible to reduce low frequency phase noises. ^ 1 dwg
