METHOD OF ELIMINATING DEAD BAND IN FIBER OPTICAL GYRO Russian patent published in 2013 - IPC G01C19/72 

Abstract RU 2472111 C1

FIELD: physics.

SUBSTANCE: dead band is eliminated by control over stability of parameters of auxiliary phase modulation and synchronisation of maximum voltage zeroing time to compensate for difference in Sagnac phases of stepped tooth voltage with half-periods of demodulation of gyro revolution signal.

EFFECT: eliminated insensitivity zones.
