Detect defects optically: understanding an optical sensing system helps improve reliability.

From: Quality | Date: May 1, 2006| Author: | Copyright information

Photosensing systems have been used extensively for detection, gaging, identification and characterization. They are used in high-speed defect detection and gaging, characterization, pattern recognition and identification. These systems are called on to perform with high reliability and performance in increasingly difficult circumstances.

Many noncontact optical sensing systems are integrated into real-time automated control systems. To improve the reliability of any automated sensing system, it becomes necessary to understand the signals generated, how decisions are made by ...
