Abstract

An optical heterodyne fiber gyro, which we recently proposed, is improved to reduce the zero-point drift. A reference interferometer is introduced in the improved configuration beside the sensing interferometer to obtain the Sagnac phase shift, which monitors the drift caused in the optical system. Experimental results demonstrate successful reduction of the drift.
