Abstract: Machine visions play a significant role in most precision alignment, attach and inspection processes in photonics automation. As the photonics industry moves towards automation, a better understanding of critical vision parameters that affect the performance of an automation system is needed. In this paper, a real life case study will be presented to demonstrate how some of the critical vision parameters affect the overall performance of the vision system.

At the same time, the experimental procedure presented could serve as a demonstration of how the performance of a vision system can be verified. Following the case study, key vision parameters such as Static Repeatability, Orientation Change, Contrast, Fiducial Quality, Camera Resolution & Camera Calibration that determine the vision system performance in the case study will be defined and discussed in details. Proper understanding and identification of these parameters will ensure that desired vision systems performance will be achieved.

Key words: machine vision, fiducial quality, photonics automation.
