title: Fiber-optic heterodyne gyroscope using two optical beams with orthogonally polarized components.
abstract: A novel scheme for a fiber-optic heterodyne gyroscope is proposed. This scheme produces two beat-photocurrent signals, including the Sagnac phase shift of opposite sign. The phase-difference measurement of these signals enables us to cancel their common phase factor but to obtain twice the Sagnac phase shift. The operation principle is verified experimentally.
