Photonics plays a role in all areas of military development: Sensing, Detecting the Enemy: Photonics Expands Strategic Vision
Sep 1, 1997 — The greatest trick in any battle is seeing the enemy before they see you. Unlike radar and other active detection systems, optical detection is mainly a passive detection system, meaning that the act of detection does not emit a tell-tale sign to...
Sensor Warns of Biological Warfare
Sep 1, 1997 — WASHINGTON -- Researchers at the Naval Research Laboratory's Center for Bio/Molecular Science and Engineering have developed a multichannel biosensor capable of providing early detection of anthrax and other lethal biological agents. Now in advanced...
Technology Transfers Both Ways
Sep 1, 1997 — In today's military, the fable of the $300 toilet seat has joined the ranks of the left-handed monkey wrench. A new program in the US military should help prevent taxpayers for paying too much for too little, while also boosting commercial...
Weapons of War:
Sep 1, 1997 — Military lasers have become the weapons that existed only in science fiction novels a generation ago. From blowing enemy missiles out of the sky to tracking enemy targets, the sheer numbers of laser weapons has prompted a new way of thinking within...
Defense Technology Aids Medicine
Aug 1, 1997 — WASHINGTON -- A combination of military and commercial technology has created a practical midwave IR spectral imaging microscope. The system developed by researchers from the National Institute of Standards and Technology and the National Institutes...
Laser Probe
Aug 1, 1997 — A joint effort among the US Department of Defense, ITT of Roanoke, Va., and Litton of Tempe, Ariz., resulted in the production of these night-vision goggles for the US Marines.
Northwest Orders Fiber Gyros
Aug 1, 1997 — Litton Industries' Aero Products division has received a $35 million contract to retrofit Northwest Airlines' inertial navigation systems installed on 33 Northwest B747 and 21 Northwest DC-10-40 aircraft. Litton will install its strapdown Ring Laser...
Report pushes US defense commercialization
Aug 1, 1997 — WASHINGTON -- A report soon to be released by the Optoelectronics Industry Development Association extols the virtues of closer connections between industry and the US Department of Defense, with particular emphasis on small-business participation....
Sensors Are Key to Missile Interceptor
Aug 1, 1997 — The Pentagon has successfully tested an infrared sensor that will act as the "eyes" of a missile interceptor, which is part of a proposed nationwide defense system against enemy ballistic missiles. The infrared sensors are designed to identify and...
US Cracks Down on Laser, Chemical Exports Used in Weapons Manufacture
Aug 1, 1997 — The US Department of Commerce has expanded its crackdown on exports beyond nuclear weapons technology to encompass materials for making chemical weapons, including uranium and lasers. Undersecretary William Reinsch said the department has begun...
American Blue Diode Laser Pulses Atop Silicon Carbide Substrate
Jul 1, 1997 — DURHAM, N.C. -- Cree Research Inc. has demonstrated a pulsed blue semiconductor diode laser that operates at room temperature -- a first step in a race for a commercial device that would greatly increase optical storage capacity.The company's 403-nm...
Boston University Opens $80 Million Photonics Center
Jul 1, 1997 — Wielding golden scissors, politicians and educators cut a ribbon and formally opened Boston University's state-of-the-art $80 million Photonics Center last month. On hand were Sens. Edward M. Kennedy of Massachusetts and Daniel K. Inouye of Hawaii....
Caveat emptor: One laser does not fit all
Jul 1, 1997 — BALTIMORE -- It's buyer beware as manufacturers of diode-pumped Nd:YAG solid-state lasers seek to replace arc-discharge lamp-pumped devices with the "all-purpose" laser. Users should carefully consider their applications before investing in the most...
Quantum Cascade Laser to Play Key Role in Gas Detection
Jul 1, 1997 — MURRAY HILL, N.J. -- A new laser-based sensor could mark a breakthrough in the detection of minute quantities of trace gases and pollutants.The exceedingly sensitive device is capable of detecting pollutants in parts per billion, according to one of...
Rome scientist Hendrickson dies
Jul 1, 1997 — ROME, N.Y. -- Brian M. Hendrickson, associate chief scientist for photonics at Rome Laboratory, died at 53 after a brief illness.Hendrickson had been with Rome Laboratory for 29 years, both in the photonics program and the Federal Scientific and...
Ultraviolet Laser Combines Steps in Wafer Doping
Jul 1, 1997 — SAN JOSE, Calif. -- An instrument that employs a laser doping process could combine the lithography and silicon doping steps in the manufacture of integrated circuits.The device, a deep-UV stepper using a technique that Ultratech Stepper Inc. calls...
US Strengthening Flat Panel Display Manufacturing Technology
Jul 1, 1997 — The United States Display Consortium, a group of flat panel display manufacturers and developers, has initiated 33 projects to bolster the US infrastructure and supply base.The consortium has committed $107 million to R&D projects over the past...
