Design and realization of the auto-measuring system of optical fiber polarization characteristics based on DSP technology

ZOU Xue-feng,FENG Li-shuang,MA Ying-jian (School of Instrument Science & Opto-electrics Engineering,Beijing University of Aeronautics and Astronautics,Beijing 100083,China)  
The basic principle of measuring the polarization characteristics of Polarization-maintaining(PM) optical fiber is introduced in this paper.Based on DSP and FPGA technology,the structure of high precision polarization detecting system is then presented with on emphasis on the structure diagrams of analog detecting circuit and digital processing circuit.Finally,a precision analysis on the experiment data is made in detail.
