opdi-tex GmbH, Eresing/Germany, transferred a technology into the fabric which has been used in automotive production for several years. A sensor with 3 measuring heads covers a swarm of wires. Each head is typically responsible for 60-80 cm, capturing the thread in this area with over 4,000 pixels. With its raw resolution of 0.2 mm, it is suitable for almost all types of fabric and threads.
Due to its scalability, it can also be used for resolutions up to a minimum of 0.05 mm.

High-resolution line scanners enable all gloss effects to be removed – even small, protruding fibers <100 μm are recognizable
Since the sensor does not touch the thread, it cannot damage it. The technology used is resistant to ambient light, partly even to sunlight. A patented retro-reflection process often dispenses with active backlighting - it is sufficient to stick a special film behind the threads. The film is as robust as a license plate on the car - and thus easy to clean and it is flat - 0.2 mm are enough.
