Laser welding gets a vision boost.

The article reports on the image-processing technique for laser welding developed by researchers at the Fraunhofer Institute for Physical Measurement Techniques in Freiburg, Germany. The technique, as reported, can monitor the welds and adjust the incident laser power with a response time of 70 ms. The technique, as reported, has a cellular neural network camera, image processing, and a feedback loop that allows real-time imaging with frame rates of up to 14 kHz.
