Automated Rockfall Recognition from Thermal Video using Computer Vision
This invention consists of an algorithm that utilizes computer vision and thermal imaging cameras to detect, track, and alert for hazardous fall events in environments with exposed and potentially unstable rock walls or structures. The Automated Rockfall Recognition system utilizes mathematical, non-machine-learning methods to identify rockfall events...

Distributed Feedback Fiber Laser Pumped by Multimode Diode Lasers
Researchers at the University of Arizona College of Optical Sciences and Canada's Carleton University recently succeeded in fabricating high reflectivity (>99%) Fiber Bragg Gratings (FBGs) into phosphate glass fibers using UV light and a phase mask technique. With this new manufacturing technique, fiber lasers can be created as single monolithic...

All-Fiber Multicore Fiber Laser Devices
Researchers at the University of Arizona have developed a compact, power-scalable, alignment-free fiber laser that takes a new approach to stabilizing phase-locked operation of multi-core fiber lasers by completely removing all free space optical components. This high-brightness, all-fiber laser package uses passive optical fiber spliced at both ends...
