Paper Abstract

We present an automatic inspection system developed to evaluate the geometric tolerance of the optical fiber connectors to a dimensional accuracy of 0.1 micron. The main part of the inspection system comprises a series of machine vision devices and laser scanning probes to measure the internal and external circle diameters along with their concentricity by making the most of advanced digital edge detection algorithms. Actual experimental results obtained through various repeatability tests demonstrate that the developed system well satisfies the required industrial demands for in-situ inspection of optical fiber connectors in real manufacturing environment.
