光纤连接器是影响光纤系统性能的重要因素。为了确保光纤与光纤良好的接触，需要对光纤连接器的端面几何形状进行定量测量。本文介绍了一种基于视觉的单光纤连接器端面几何形状自动测量系统。该系统的光学系统基于Mirau物镜干涉仪，利用相移技术获得了连接器端面的三维轮廓。应用图像处理技术自动找到纤维中心，并检索连接器端面的几何参数，如曲率半径、顶点偏移量和突起或底切。实验结果证明了该系统的可行性。
Fibre optic connectors are an important factor in the performance of fibre optical systems. In order to ensure good fibre-to-fibre contact, the endface geometry of fibre connectors needs to be measured quantitatively. In this paper, we present a vision-based automatic measurement system for the measurement of the endface geometry of a single-fibre connector. The optical set-up of the system developed is based on a Mirau objective interferometer, and a 3D profile of the connector endface is obtained by using phase-shifting techniques. Image-processing techniques are applied to automatically find the fibre centre and retrieve the geometric parameters of the connector endface, such as radius of curvature, apex offset and protrusion or undercut. Experimental results have demonstrated the feasibility of the proposed system.
