摘　　要：We introduce an all-fiber stationary phase shifter for a fiber-optic gyroscope(FOG)which simultaneously provides phase shifts of opposite signs in different cores of the dual-core optical fiber.We propose a new dual-core fiber-optic gyroscope(DCFOG)in which different cores of the dual-core optical fiber provide independent rotation rate measurements.The device enables implementation of a differential scheme,which ensures the stability of the measured phase shift.As a computer simulation result,the accuracy of the rotation rate sensing is increased by up to 10 times at typical noise levels.
