  • Abstract
    A new all-PANDA-fibre gyroscope is reported. All components such as the coil, the phase modulator, the 3 dB coupler and the polariser were constructed by the PANDA fibres. The extinction ratio of the fibre-type polariser was 43 dB, with the insertion loss smaller than 0.04 dB when the fibre was bent by the radius R = 10 cm. For long-term behaviour, the peak-to-peak fluctuation of 0.5 deg/h was observed with 40 s integration time
