FIELD: physics.
SUBSTANCE: device has an optical radiation source, a photodetector, a first optical beam splitter, a mode filter based on a polarising light guide with high linear birefringence, a polariser, a second optical beam splitter, a phase modulator and a multi-turn fibre sensitive coil made from a polarising light guide.
EFFECT: high accuracy of the fibre-optic gyroscope by reducing parasitic phase difference in the interferometer.
