Abstract

The test results of a prototype serrodyne closed-loop interferometric fiber optic gyroscope are reported. The rotation sensor used a low-coherence superradiant diode at 0.85 microns wavelength with a polarization-maintaining sensing coil, polarizer and loop coupler. A wide bandwidth Ti:LiNb0₃ phase modulator was used to provide bias modulation and serrodyne frequency shifting. Performance of the sensor before and after loop closure is discussed. No degradation of the random walk or bias stability was noted with loop closure. The scale factor and dynamic range were improved. Various contributors to scale factor error are discussed.
