Lidar Maps Faults Near Lake Tahoe
CARNELIAN BAY, Calif., May 25, 2012 — Faults west of Lake Tahoe, Calif., now pose a substantial increase in the seismic hazard assessment and potentially could generate earthquakes with magnitudes ranging from 6.3 to 6.9, according to a new US Geological Survey study.
RIO Awarded Phase 2 Contract for Space Lidar
SANTA CLARA, Calif., May 2, 2012 — The laser manufacturer was awarded a Phase 2 SBIR contract from NASA to further develop its single-frequency narrow-linewidth semiconductor laser technology in the 1064-nm spectral region for space lidar.
Exploring Optics Underwater with an iPad
STENNIS SPACE CENTER, Miss., April 11, 2012 — A new rigid frame device that securely holds a high-speed camera and an iPad can obtain field measurements of optical turbulence structures and quantify their impact on underwater imaging and beam propagation.
Lidar uncovers hidden earthquake damage
MEXICALI, Mexico, and DAVIS, Calif. – A new tool reveals how earthquake faults behave and how, down to a few inches, earthquakes change the landscape. A team of geologists from the US, Mexico and China has reported the most comprehensive before-and-after picture yet taken of an...
Lasers Boost Standoff Sensing
OAK RIDGE, Tenn., March 26, 2012 — A dual-laser pump-and-probe system developed at Oak Ridge National Laboratory enables the identification of biological agents and chemicals from a distance.
Photonic Sensors Help Keep Earth Clean, Green
Mar 1, 2012 — Spectroscopic, fiber optic sensing, and light detection and ranging (lidar) technologies increasingly are being employed in the wind and geothermal energy sectors; in making fossil fuel exploration, extraction and distribution as well as...
Lasers Reveal Hidden Earthquake Damage
DAVIS, Calif., Feb. 14, 2012 — New airborne lidar equipment reveals how earthquakes change the landscape down to a few inches, and shows how earthquake faults behave.
Clear Align Receives Laser Patent for Intelligence
EAGLEVILLE, Pa., Dec. 1, 2011 — Custom imaging and laser systems manufacturer Clear Align received a patent for laser technology that is suitable for various intelligence, surveillance and reconnaissance applications. The US Patent and Trademark Office granted the company Patent...
Photonics on ice!
Dec 1, 2011 — Summer comes to the icy vistas of the Antarctic shores. The winds die down a bit, and the temperature climbs (sometimes to above freezing). Most remarkable is the burgeoning population of the unusual bipeds, all puffed up in their striking, yet...
Satellites, Remote Sensors Shed Light on Subterranean Structures
Jun 17, 2011 — We all know that the lost city of Tanis is “one of the possible resting places of the Lost Ark” … those of us, anyway, who grew up thrilling to the exploits of the swashbuckling academic Indiana Jones. But now archaeologists may...
Laser Beam Steering Made More Efficient
RALEIGH, N.C., May 9, 2011 — The ability to precisely control the direction of a laser beam in an energy-efficient and inexpensive way has been discovered by researchers from North Carolina State University. "In many cases, it is much easier to redirect a laser beam at a...
Sniffing out bombs and pollutants from a distance
PRINCETON, N.J. – A breakthrough in laser sensing technology could allow soldiers to detect hidden explosives from a distance and scientists to better measure airborne environmental pollutants and greenhouse gases. The new laser sensing technology developed by...
‘Air Laser’ Sniffs Bombs, Pollutants from Afar
PRINCETON, N.J., Feb. 1, 2011 — A new laser sensing technology that generates a laser beam out of thin air may allow soldiers to detect hidden bombs from a distance and scientists to better measure airborne environmental pollutants and greenhouse gasses. Researchers at Princeton...
On the Road with Junior: A tale of optics and driverless cars
Oct 15, 2010 — Once accessible only to the likes of David Hasselhoff and Batman, autonomous driving is now finding its way into a range of consumer vehicles. Here, in following a car named Junior and its various progeny, we trace the recent history of driverless...
Electron-Multiplying CCD for Lidar Applications
Aug 1, 2010 — Until recently, only photomultiplier tubes were suitable for low-light imaging. However, this technology and associated poor spatial resolution were not suited to scientific applications. Solid-state devices such as image intensifiers or...
Adding Fiber Pays Off for Industry
Jul 1, 2010 — For Electro Scientific Industries Inc. (ESI) of Portland, Ore., getting fiber into its diet has been one key to success. Among other things, the company makes a line of micromachining systems for the semiconductor, flat panel display, photovoltaic...
GST Hires Longtime NASA Scientist
