摘要

保偏光纤偏振轴的检测和对准是保偏光纤应用中的关键技术.为提高基于端面成像的偏振轴检测方法的检测精度, 以熊猫型保偏光纤为研究对象, 采用基于曲面拟合的亚像素边缘检测算法和椭圆拟合算法提高检测的准确度, 采用多次测量取平均法提高检测的精确度;利用检测结果的正态分布特性, 提出一种基于概率的偏振轴定轴方法.搭建了保偏光纤自动定轴系统并进行实验, 准确性验证实验结果表明：亚像素边缘检测方法平均可以减小45%的偏差, 而拟合椭圆相较拟合圆平均可以减小15%的偏差;精确性验证实验表明采用多次测量取平均的方法可以有效减少检测结果的离散程度;定轴实验的结果表明, 基于概率的偏振轴定轴方法可以达到优于0.1°的定轴准确度.

Abstract

The detection and alignment of polarization axis is a key technology in PMF’s application.In order to improve the accuracy of the end face detection of polarization axis,a sub-pixel edge extraction method based on surface fitting was proposed to improve the accuracy and the normal distribution of the detection result was used to improve the precision.Based on the normal distribution of the detection result,a aligning method based on normal distribution was put forward.An automatic aligning system was established.The experiment shows the sub-pixel edge extraction method can decrease the error by 45% and the ellipse fitting can reduce the error by 15%.The alignment experiment figures out that the bias of aligning method based on probability is less than 0.1°.
