Cognex Corp. has introduced a machine vision system for automatic detection and measurement of scratches, cracks and spots that form on fibers during polishing. Fiber-Inspect can be used in conjunction with existing manual inspection systems or integrated into OEM custom-designed automated systems. The company says its software algorithms enable the system to detect fiber-end defects smaller than a single micron, even when there is poor contrast between defect and background. The system can classify defects by type to help users understand problems in the polishing process. The package includes the software, a frame grabber and a Windows-based graphical user interface.
