Ei. Alekseev et En. Bazarov, COMPENSATION OF EXCESS NOISE IN A FIBEROPTIC GYROSCOPE WITH A 3X3 DIRECTIONAL COUPLER, Technical physics letters, 23(8), 1997, pp. 589-590
It is shown theoretically that the excess noise of the radiation sourc
e can be compensated in a fiberoptic gyroscope with a 3X3 ring directi
onal coupler and a differential amplifier at the exit. This noise is o
ne of the main factors limiting the precision of a fiber-optic gyrosco
