Lidar Scanning May Aid Forest Monitoring, Management
JOENSUU, Finland, Dec. 7, 2015 — A mathematical method usually employed in economics for studying income inequality has been applied to the study of tree-size variation using lidar data. Researchers from the University of Eastern Finland have identified and analyzed indicators for expressing size differences among neighboring trees and developed methods to obtain these indicators — which measure characteristics such as stem density — using lidar technology. In this method, forests were scanned with a
Quanergy Develops Lidar for Self-Driving Cars
SUNNYVALE, Calif., Nov. 18, 2015 — Quanergy Systems Inc. plans to release the first solid-state lidar sensor for self-driving cars in 2016. The sensor contains an integrated circuit that scans in every direction without any moving parts on both the macro- and microscale, creating a...

GREENBELT, Md., Aug. 27, 2015 — Ravenous insects smaller than a penny continue to migrate from the Southeast, threatening to destroy millions of pine and ash trees in the Northeast. Now NASA has teamed with the U.S. Forest Service to combat the problem using an array of optical...
Lidar Firm Rechristened Teledyne Optech after Acquisition
THOUSAND OAKS, Calif., April 30, 2015 — Teledyne Technologies Inc. has taken full ownership of Optech Inc., a Canadian manufacturer of laser-based survey and digital imaging instrumentation. Terms of the transaction, which was carried out through Teledyne subsidiary of Teledyne Dalsa...
Lidar Chip Offers Mobile 3-D Scanning
PASADENA, Calif., April 6, 2015 — A tiny lidar device could turn mobile phones into powerful 3-D scanning devices. Based on a silicon chip less than a square millimeter in size, the nanophotonic coherent imager (NCI) provides the highest depth-measurement accuracy of any such...
Neptec 3-D Lidar Sensor System Aims to Improve Mine Operations
OTTAWA, Ontario, Canada, Feb. 18, 2015 — Neptec Technologies Corp. has completed proof-of-concept testing on a new 3-D lidar sensor system designed to help truck drivers and shovel operators for mining operations. The 3DRi Spot Assist system uses multiple lidar sensors mounted on the...
Exelis to Adapt Lidar System Under $3.5M NASA Contract
ROCHESTER, N.Y., Jan 6, 2015 — Exelis will modify its multifunctional fiber-laser lidar (MFLL) system for aerial carbon dioxide measurements under a $3.5 million NASA contract. The company is collaborating with project leader professor Dr. Kenneth Davis of Pennsylvania State...
Smaller, Faster Lidar Could Map Seafloor from Aerial Drones
ATLANTA, Dec. 15, 2014 — A lidar system light enough to fly on a drone and fast enough to process highly distorted signals in real time could enhance underwater mapping and security. Firing a high-power green laser 10,000th of a second, a prototype built at the Georgia Tech...
Algorithm Speeds Lidar Assessment of Landslide Risk
CORVALLIS, Ore., Nov. 21, 2014 — Computer algorithms could turn lidar surveying systems into powerful tools for assessing and potentially preventing landslides. Created by researchers at Oregon State University and George Mason University, the Contour Connection Method (CCM) and is...
Smile and Say, ‘Drone!’
Oct 6, 2014 — Any photographer will tell you that if it were possible to grow an extra set of hands, he would. As simultaneous scientists, artists and packhorses, photographers must know their equipment inside and out, but they must also be prepared to change...
Video: Drone System Aids Photographic Lighting
CAMBRIDGE, Mass., July 17, 2014 — A small, autonomous helicopter can direct lighting just where a photographer needs it. Researchers at MIT and Cornell University developed the drone system to respond to the movements of a photographer and her subject using lidar and input from the...
