摘要
依据IEC 60793-1-21:2001、GB/T 15972.21—2008《光纤试验方法规范第21部分:尺寸参数的测量方法和试验程序——涂覆层几何参数》所提供的涂覆层几何参数测量方法,开展光纤涂覆层几何性能测试系统的设计工作。借助数字图像处理技术,对被测光纤在不同旋转角度下的成像进行深入分析,通过有限点拟合光纤端面,对光纤的几何参数,如包层、一次涂覆层、二次涂覆层等展开测量,并进行分析及对比验证。结果显示,该测试系统的测量结果与国外同类测量设备基本相符,具备较高的准确性。
Design and development of a geometric performance testing system for optical fiber coating layer was conducted,based on geometric parameter measurement methods for coating layer stipulated in IEC 60793-1-21:2001 and Specification for Optical Fibre Test Methods—Part 21:Measurement Methods and Test Procedures for Dimensions—Coating Geometry(GB/T 15972.21—2008).Digital image processing technology was employed to conduct in-depth analyses of the tested optical fiber images at various rotation angles.Through finite point fitting of the optical fiber end face,geometric parameters of the optical fiber were measured,including cladding,primary coating layer,and secondary coating layer.Test results were then analyzed and verified through comparison.The findings indicated that test results of the system were largely consistent with those of similar foreign measuring equipment,thereby demonstrating high accuracy.
