OPTICAL CIRCUIT OF RING INTERFEROMETER FOR FIBRE-OPTIC GYROSCOPE Russian patent published in 2013 - IPC G01C19/72

Abstract RU 2486470 C1

FIELD: physics.

SUBSTANCE: method is realised through more efficient filtering of higher modes at the input and output of the optical circuit of a ring interferometer of a fibre-optic gyroscope using a piece of a light guide with defined parameters, which is placed between an optical radiation splitter and a polariser.

EFFECT: high accuracy of the fibre-optic gyroscope.
