| Abstract: | An instrument with a white-light Michelson interferometer has been designed to measure the crosscoupling in birefringent polarization maintaining fiber. A mathematical model is presented based on the structure of the system.Analysis and emulation are implemented for the influence of the system SNR on the testing accuracy of coupling intensity and coupling position,including its magnitude and movement trend. It′s indicated when the SNR is larger than 32 dB, the demand of polarization coupling test is satisfied. |
