FIBRE-OPTIC ANGULAR SPEED METRE Russian patent published in 2013 - IPC G01C19/72 

FIELD: measurement equipment.

SUBSTANCE: metre comprises two amplifier-converters (AC1 and AC2), a sync pulses shaper (SPS), a fibre-optic contour, two phase modulators installed at the ends of the fibre circuit, and optically coupled input coupler, a polariser, and a circuit coupler, by outputs optically connected with the ends of the fibre circuit, a depolarisator, a receiving module (RM), a source of radiation, the output of which is optically coupled via the depolarisator with the input of the input coupler, a photodetecting module (PDM), with its photodiode optically coupled with the output of the input coupler, a phase sensitive rectifier (PSR), and also a switchboard, with inputs connected to the outputs of the AC1 and AC2. The FOASM may be used as a multi-channel version with arbitrary arranged axes of sensitivity.

EFFECT: reduced power consumption of a multi-channel version, reduced error of a scale ratio.
