Automatically detect and measure fibre
scratches
Cognex has introduced FiberInspect, a machine vision system specifically designed to automatically detect and measure scratches, cracks and spots on fibres that form during the polishing process.
Cognex has introduced FiberInspect, a machine vision system specifically designed to automatically detect and measure scratches, cracks and spots on fibres that form during the polishing process The new system, which can be used in conjunction with existing manual inspection systems, or integrated by OEMs into custom-designed automated systems, will help increase fibre cable yield by detecting defects with far greater speed, accuracy, and objectivity over current manual approaches

Cognex has introduced Display Inspect - a machine vision software and hardware package for inspecting displays, keypads, and enclosures on LCD and LED display-based products.
"With manual inspection methods, it may take an operator up to a minute to thoroughly examine a close-up image of a fibre end for defects.
Because the process is highly subjective, operators may visually interpret defects in different ways, resulting in the false acceptance of defective cables, which may fail in field use.
The new FiberInspect system, developed by our Fibre Optic Products Team, can accurately and quickly determine if a cable is good, bad, or needs to be re-polished, thereby eliminating guesswork and improving throughput." said Justin Testa, Senior Vice President of Marketing for Cognex.
Utilising proprietary, unique software algorithms, FiberInspect can detect fibre end defects smaller than a single micron, even when there is poor image contrast between the defect and background.
In a typical application, an image of a polished fibre end is acquired by a fibrescope camera and transferred directly to the FiberInspect system, which analyses the image, graphically highlights each defect, and provides data about the position and size of each.
The system can also be set up to classify defects by a certain defect type, such as a crack, to help users better understand problems that exist in the polishing process.
FiberInspect features a Windows-based graphical user interface, making it easy for users to operate the system.
Accept/reject criteria are entered into simple dialogue boxes, and the system automatically adapts to the fibre type being inspected.
Additionally, the system enables defects to be graphically highlighted in user-defined colours, making it easier for operators to view specific types of defects.
The FiberInspect package consists of advanced machine vision inspection software, a Cognex MVS-8100 frame grabber, and a Windows-based graphical user interface.
A Visual C++ software development kit version of the product is also available for OEMs. Request a free brochure from Cognex UK ...
