Paper Abstract

The experimental demonstration of an all-fiber resonator optic gyroscope employing a spliceless PM-fiber resonator with 90 degree(s) polarization rotation in the lapped coupler is presented. A Frequency Modulation spectroscopy technique has been demonstrated for rotation sensing using two piezoelectric transducer phase modulators. The short term bias stability better than 16 degree/hr with integration time of 10 sec has been obtained. The main error sources of optical system are discussed and some reduction measures are suggested.
