Research In Auto Azimuthal Alignment Method for Panda Fiber

Polarization observation by lens-effect-tracing (POL) method was widely used in azimuthal alignment System for Polarization-maintaining Fiber for its simplicity and accuracy. In this paper, the pol method was studied by computer simulation, an improved method based on the five character points was presented to achieve higher accuracy for the auto azimuthal alignment system. And the new method was proved to be more accurate and more fit for the auto alignment system.
