Near-perfect optical absorber developed
CAMBRIDGE, Mass. – A tunable device coated with a film 100 times thinner than the wavelength of incident light absorbs 99.75 percent of a specific mid-infrared band on demand, potentially expanding thermal detection and energy harvesting applications. Designed by scientists at the School of Engineering and Applied Sciences (SEAS) and the University of California, San Diego, the near-perfect absorber is composed of a 180-nm-thick layer of vanadium dioxide (VO2) on a sheet of sapphire, a standard substrate for g...
Active and Passive Modes in One IR Camera
EVANSTON, Ill., Jan. 21, 2013 — A new approach that integrates active and passive infrared (IR) imaging capability into a single chip has paved the way toward lighter, simpler dual-mode active/passive cameras with lower power dissipation.
Surveillance System Enables 24-Hour Target Acquisition
Dec 1, 2012 — A new multidetector system uses multiple-wavelength sensors and lasers for rangefinding, target spotting and target illumination. Multisensor detectors can be of great use to surveillance systems, whether they use intensified CCD, CMOS,...
Material Absorbs Nearly 100% of IR Light
CAMBRIDGE, Mass., Nov. 27, 2012 — An ultrathin, tunable device developed at Harvard absorbs 99.75% of infrared light on demand and, when activated, looks like a black blob to IR cameras. The near-perfect absorber could expand the possibilities for energy harvesting and thermal...
The Optics of Paranormal Activity
Oct 18, 2012 — The site of the now-shuttered Camp Evans, in Wall Township, N.J., has played host to the Ku Klux Klan, former Nazi scientists and Senator Joseph McCarthy, and is said to be among the most haunted in the state. A group called Behind the Wall...
Telops Lands Leak Detection Contract in China
QUEBEC CITY, Oct. 9, 2012 — Telops has received a leak detection and identification system contract from Sinopec Group of Beijing.
DLC Coatings Enhance IR Cameras
Sep 1, 2012 — Applying new diamondlike carbon multiple-layer coatings to front-surface forward-looking infrared lens assemblies drastically reduces the Narcissus effect without compromising durability. In Greek mythology, the hunter Narcissus was renowned...
ULIS Invests €20M in New IR Sensor Facility
VEUREY-VOROIZE, France, Aug. 7, 2012 — On its tenth year anniversary, the infrared imaging sensor manufacturer announced a €20 million investment in a new state-of-the-art facility to meet increasing market demands for infrared technology.
IR Imaging Optics Meet Varied Needs
Aug 1, 2012 — Infrared camera technology spans a wide range of the electromagnetic spectrum, with results that vary with the waveband. Although there is some overlap of applications between the different infrared subbands and associated sensor technologies, it is...
Something in the air
Jul 1, 2012 — The recent article on airglow (“The Night Glows Brighter in the Near-IR,” April 2012) contains misleading statements and a generally sloppy treatment of radiometric units of measure. Some behind-the-scenes math by the authors and more...
193-nm Lithography Opens Doors for Diffractive Micro-Optics
May 1, 2012 — Design considerations and fabrication affect performance for a near-IR large-angle homogenizer for use in 3-D sensors based on time of flight. The field of diffractive micro-optics is playing an increasingly important role in today’s...
First Light of Mosfire Celebrated
WAIMEA, Hawaii, April 12, 2012 — The Mosfire instrument observed the universe with its near-infrared sensing eyes for the first time on April 4, capturing images of a pair of interacting galaxies known as The Antennae. The new device will enable astronomers to study space phenomena...
The Night Glows Brighter in the Near-IR
Apr 1, 2012 — The night sky is never absolutely dark, even after removing the influence of starlight and diffused sunlight from the other side of the globe. Spectral irradiance, caused by airglow, is several times stronger in the 900- to 1700-nm band than in the...
