The team from the School of Information and Communication Engineering at the University of Electronic Science and Technology of China has proposed for the first time a laser radar instrument based on the dispersion Fourier transform method, forming a new demodulation mechanism. This instrument breaks through the cross limitations of measurement speed, accuracy, and distance, and has unique advanta...
At last month’s LASER World of Photonics exhibition in Munich, Germany, industrial solutions and laser giant Trumpf presented a new materials processing laser system solution specified to improve welding processes.The system combines several sensors that monitor all process steps during laser welding. An integrated AI quality control system checks the weld seams, for example, and OCT (optical cohe...
Imagine being able to carry a 3D printer with you and quickly create low-cost objects, such as fastening bicycle wheels or parts needed for critical medical surgeries. Scientists from the Massachusetts Institute of Technology (MIT) and the University of Texas at Austin have combined silicon photonics and photochemical technology to successfully develop the first chip based 3D printer, taking a cru...
