Polarization axis should match when two Panda polarization maintaining fibers connect

in order to getting high accuracy identification of the polarization axis

an accurate computer image identification algorithm was presented to identify the polarization axis of the Panda polarization maintaining fiber. To validate the algorithm

program was developed to perform image analysis and processing with LabVIEW software. The practical data of application indicates that they are very useful to improve the identification precision of polarization maintaining fiber and raise productivity of fiber connector with the technologies of computer-aided vision detection and modern measurement & control.
