A closed loop optical fiber interferometer is used in sensing a quantity, Q, by applying a time varying or modulated measure of, Q, asymmetrically to the closed loop (24) and detecting phase shift between two counterpropagating optical signals in the closed loop. The closed loop (24) can be used as the sensing element or a separate sensor (68, 70) can develop a time varying signal which is then applied to the closed loop interferometer.
