CANTON, Ohio, April 10 -- The Timken Co. said it will make laser ultrasonic technology commercially available to steel manufacturers. The technology, a gauging system for manufacturing seamless steel tubing, completed a testing period at the company's Gambrinus steel plant. "The capabilities of this laser ultrasonic system extend far beyond those of previous radiation gauging techniques," said Raymond V. Fryan, director of process improvement/alloy steel. "Most importantly, measuring the full length of the tube during manufacturing not only verifies quality of the entire tube, it also reduces...Read full articleRelated content from Photonics MediaArticlesFreeform Illuminators Spur Computational Microscopy Efficiency GainsTo further the use of programmable illumination for computational microscopy methods, researchers at the University of Connecticut constructed, calibrated, and tested freeform illuminators in...Vision-Spectra.com March 2023 IssueMobile Sensor-Scanner Gauges Engine Condition Indicators in 3DResearchers at the Fraunhofer Institute for Applied Optics and Precision Engineering IOF (Fraunhofer IOF) have developed a portable sensor-scanner for building comprehensive 3D models of complex...Photonics Spectra July 2023 IssueHow AI Is Advancing the Manufacture of Photonic SystemsMany trends in the manufacture of photonic systems are well known: miniaturize and integrate components, scale-up batch sizes, and, increasingly, expand automated and sustainable manufacturing.
