An automated fiber inspection machine was developed. The 3 images below are of an MT fiber connector that is scratched and dirty. Physical constraints required the custom optics to have small NA and long working distance which caused a slightly blurred image as seen in the upper left. Deconvolving the image with the PSF creates the image on the upper right. The bottom image shows the machine vision defect detection output.
A 3-DOF machine was designed to meet the tight phyiscal constraints, allowing the vision system to inspect each connector at the back-plane of the router.
