Infrared Grain Analyzer Goes with the Flow
Dec 1, 1999 — Knowing the exact quality of grain can increase profits for farmers. Corn containing a high oil content and wheat with a high level of protein can demand higher prices. Current methods of measuring oil and protein content, based on reflected near-infrared light, require benchtop instruments that can cost up to $60,000 and need frequent calibration. Because these stationary instruments measure small samples taken from a single load, the results only indicate how well those samples represent the...
New Spectroscopy Technique Detects Trace Samples
GAITHERSBURG, Md. -- GAITHERSBURG, Md. -- A new approach to surface spectroscopy has proved 100 times more sensitive than current methods and may eventually be capable of identifying a strand of a deadly virus or a single particle of explosive residue. Spectroscopy in...
Spectrometer Makes Filmmakers See Red
Dec 1, 1999 — Cinematographers hate fluorescent lights. Although these light sources look more or less normal to the human eye, they show up as green on film. Worse, they impart a weird and unhealthy greenish cast to everything they illuminate, including human...

Nov 29, 1999 — DUNEDIN, Fla., November 29, 1999 -- Ocean Optics Inc. announced it has acquired the assets of Hauppage, N.Y.-based Continental Optical Corp., a manufacturer of precision optical components and coatings that earned nearly $2 million in sales in...
Blue Laser Diodes Used in Spectroscopy
Nov 1, 1999 — A group at Bonn University in Germany has employed a laser spectrometer based on the InGaN blue laser diodes produced by Nichia Chemical Industries Ltd. in Anan, Japan. The device incorporated a turnkey commercial laser system developed by TuiOptics...
Crime Labs Advance with Photonics
Nov 1, 1999 — The Pennsylvania Commission on Crime and Delinquency in Harrisburg has awarded $1.8 million in federal block grants to Allegheny County and state crime labs for the purchase of high-tech equipment. Gov. Tom Ridge, who also earmarked nearly $1.7...
Trio Closes In on Remote Chemical Sensor Project
ALBUQUERQUE, N.M. — A collaboration among Sandia National Laboratories, the Massachusetts Institute of Technology in Cambridge and the Honeywell Technology Center in Minneapolis promises to produce a functioning prototype remote sensor by 2001 that will allow a person...
Algorithms Improve Spectral Imaging
Oct 1, 1999 — An imaging spectrometer in an airplane or satellite can picture the Earth’s surface while simultaneously detecting the broad range of radiation wavelengths that emanate from each pixel. More than 40 models of imaging spectrometers are in use...
Combined Spectroscopies Simplify Oil Detection
ERLANGEN, Germany -- ERLANGEN, Germany -- Mineral oils and fuels keep the world going, but they may also severely contaminate the ground and water. Laser-induced fluorescence spectroscopy has become a reliable tool for detecting such contamination, particularly for in...
Grating May Improve Spectrometers
TROY, N.Y. — Spectrometer manufacturers seeking to reduce the size and cost of their instruments may benefit from an innovation utilizing microelectromechanical systems technology. InterScience Inc. has developed a compound optical grating that could provide...
Chandra Delivers First Images
Aug 30, 1999 — CAMBRIDGE, Mass., Aug 30 -- The Chandra X-ray Observatory, NASA's newest and most powerful x-ray telescope, has delivered its first images. Chandra produced an enhanced view of the Cassiopeia A Supernova Remnant using a 5000-s exposure of the...
Hyperspectral Aerial Imaging May Conquer Canker
IMMOKALEE, Fla. — Airborne hyperspectral imaging, a military technology originally designed to pick out camouflaged vehicles from surrounding foliage, may soon help detect a different concealed enemy: citrus canker. This contagious bacterium causes citrus trees to...
Near-IR Technique Sheds Light on Kinetic Reactions
Aug 1, 1999 — Chemists at Marquette University in Milwaukee have used a multispectral imaging spectrometer constructed with an acousto-optic filter and an InGaAs focal plane array to study the kinetics of curing an epoxy resin. The researchers’ results...
Sensor Cultivates Agricultural Markets
DÜLMEN, Germany -- DÜLMEN, Germany -- Each spring, a crop is planted down on the farm operated by Hydro Agri. And each fall, along with the produce, researchers reap data on the effectiveness of various fertilizer materials. While these materials optimize the...
Dual-Beam Spectrometer Doesn’t Color Colorimetry
Jul 1, 1999 — Matching the color of an automobile’s plastic trim to its painted metal finish is difficult enough when the work is done in the same factory. Consider that these parts often are manufactured and processed in different factories or even on...
Stopped-Flow Device Improves Time-Resolved FTIR
Jul 1, 1999 — Chemists have relied on time-resolved Fourier transform infrared spectroscopy to investigate chemical reactions for years. Most of those reactions, however, were initiated externally by a laser or followed at a single wavelength. Although it is...
Varian, Seiko Instruments Sign $6 Million Agreement
Jul 1, 1999 — PALO ALTO, Calif., July 1 -- Varian, Inc. has signed a reseller agreement with Seiko Instruments Inc. (SII) of Japan. Under the three-year contract, valued at a minimum of $2 million per year in sales, SII will resell Varian's Vista line of...
ESA Signs Contract for Mars Mission
Jun 22, 1999 — PARIS, France, June 22 -- The contract for the launch of the European Space Agency's Mars Express--Europe's first mission to Mars--has been signed by Roger Bonnet, the Director of the ESA's Scientific Programme, and Jean-Yves Le Gall, President of...
Astronomers Pinpoint Birth of Comet Hale-Bopp
Jun 21, 1999 — GODDARD SPACE FLIGHT CENTER, June 21 -- A team of astrophysicists has produced the most precise measurement to date of a comet's ratio of carbon monoxide to water. As reported in the magazine Nature, the researchers, from the University of Notre...
Russian Researcher Proposes New Spectroscopy Excitation Source
Jun 1, 1999 — One difficulty with Cr4+ and Ti3+ lasers is the delay between pumping and lasing pulses. This delay poses problems for spectroscopy, which needs an excitation source that has high temporal stability with respect to the pumping pulse position. Now a...
Spectroscopies Offer Integrated View
LOS ALAMOS, N.M. — Two scientists who integrated data from four spectroscopy methods have found an innovative way to test hazardous materials and aging nuclear weapons stockpiles. The technology will provide images of heterogeneous materials that will allow scientists...
IR Spectroscopy Analyzes Polycyclic Aromatic Hydrocarbons
May 1, 1999 — Scientists have tried for years to identify the matter that exists between stars. Now a Stanford University research team may be closer to reaching that goal. The group exposed polycyclic aromatic hydrocarbons in ice to ultraviolet radiation under...
Raman Spectroscopy Helps to Decrease Engine Emissions
NASHVILLE, Tenn. -- NASHVILLE, Tenn. -- Engineers at Vanderbilt University are using Raman spectroscopy to analyze combustion in direct injection gasoline engines -- research that could lead to decreased pollution. Direct injection engines differ from conventional...
IR Reveals Evidence of Galactic Collisions
Apr 29, 1999 — COLUMBUS, Ohio, April 29 -- Astronomers from Ohio State University used infrared telescopes to discover that collisions and near-collisions between spiral galaxies are more common than had been suspected. Professor Jay Frogel and Paul Eskridge, a...
