GRAVITATION-WAVE DETECTOR Russian patent published in 2000 - IPC

FIELD: detection of low-frequency periodic gravitation-wave signals from dual relativistic astrophysical objects. SUBSTANCE: insertion of correlation negative feedback from output of detector to input of one of resonators of double-resonator laser system of triangular configuration having spatially non-equivalent loop with common active and reflecting elements and of correlation positive feedback to input of another resonator ensures its transformation into active correlation comb adaptive accumulation filter of gravitation wave signals whose operation is equivalent to operation of gravitation wave antenna with processing of signals. EFFECT: enhanced noise immunity of detector. 2 dwg
