METHOD OF LOW-FREQUENCY PHASE MODULATION FOR STABILISATION OF SCALE FACTOR OF FIBRE GYROSCOPE Russian patent published in 2009 - IPC G01C19/72

Abstract RU 2343417 C1

FIELD: physics, measurement.

SUBSTANCE: invention refers to fibre optics and can be used for design of fibre gyroscopes and other physical sensors. Accuracy of fibre gyroscope is increased due to higher stability of scale factor by equality U_Pη=2π radian, where U_P is peak value of compensating step phase saw, and is efficiency of integrated optical phase modulator.

EFFECT: higher accuracy of fibre gyroscope.
