LASER GYROSCOPE Russian patent published in 2001 - IPC

FIELD: measurement technology. SUBSTANCE: invention can be recommended for measurement of angular velocity and small variations of angular velocity of rotation, for instance, angular velocity of rotation of the Earth. Two-resonator laser system of pentagon configuration is supplemented with geometrically non-equivalent circuits of new elements such as five piezoelements of direct effect transforming mechanical vibrations to electric oscillations, five piezoelements of inverse effect transforming electric oscillations to mechanical vibrations which are anchored in pairs with working edges, phase detector, quartz heterodyne, passive noise autocompensator and five correlators. Their relative positions with regard to known elements of gyroscope, electric couplings between them and known elements form active correlation autocompensator of mechanical vibrations of reflectors. EFFECT: enhanced noise immunity of laser gyroscope. 1 dwg
