Abstract

One of the major error terms in the fiber optic gyro is the polarization crosscoupling in the components. This coupling has been analyzed with a white-light Michelson-interferometer with which position-resolved crosscouplings lower than -60 dB can be measured. We have analyzed sensor coils and pigtailed integrated-optic-chips to optimize winding and pigtailing. Also the extinction ratio of different types of polarizers have been measured.
