摘要
The polarization extent of polarization-maintaining fiber depends on incident status of polarization light, to maintain polarization status of the polarization light, requiring the polarization status of the polarization light to coupling and accord with fast(low) axis direction of polarization fiber. Thus in polarization-maintaining dual fiber collimator, packaging accuracy of the dual pigtail affects polarization capability of the polarization-maintaining collimator directly. In this paper, researched and analyzed the effect that the packaging accuracy of the dual pigtail to polarization capability of the polarization-maintaining collimator, and indicated that cat eyes' perpendicular degree of the dual pigtail was main factor. Based on machine sight, collected the end image of the dual pigtail by CCD camera, and established examine model of cat eyes' perpendicular degree, achieved image processing and examined cat eyes' perpendicular degree by VB program, examinable precision is 0.5 degree. This method was applied in industrial packaging.
