Paper Abstract

Traditional inspection methods for single-mode multi-fiber optical connectors include high magnification imaging equipment, which operate in stationary or stepper mode. The need for high precision combined with the requirement for increased throughput make these systems inefficient in the current production environment. Industry requirements are pushing towards better performance and yield as competition and pressure on the bottom line increase. A new approach, which incorporates a line-scan camera, combined with submicron-resolution optics and linear motion encoders, increases both the precision and the throughput in part inspection. Orifice morphology, as well as both relative and absolute position, can now be characterized with accuracy and repeatability measured in nanometers. Automation of batch processing for inspection enables 100% testing without impeding process cycle times. Connectors can be inspected both prior to assembly and after insertion of the fibers, allowing for part disposition further upstream in the production process. This paper will describe the line-scan-based machine vision inspection system, including considerations for image improvement through both hardware and software modifications. System capabilities and limitations will be discussed.
