Hearing the telltale sounds of dangerous chemicals
New photoacoustic technique detects multiple nerve agents simultaneously
16-08-2012
To warn of chemical attacks and help save lives, it's vital to quickly determine if even trace levels of potentially deadly chemicals—such as the nerve gas sarin and other odorless, colorless agents—are present. U.S. Army researchers have developed a new chemical sensor that can ...
Diamonds are a laser's best friend
21-09-2009
Tomorrow's lasers may come with a bit of bling, thanks to a new technology that uses man-made diamonds to enhance the power and capabilities of lasers. Researchers in Australia have now demonstrated the first laser built with diamonds that has comparable efficiency to lasers built with other ...
Engineering algae to make fuel instead of sugar
Optics Express research describes how tiny organism can make biofuel
18-12-2008
In pursuing cleaner energy there is such a thing as being too green. Unicellular microalgae, for instance, can be considered too green. In a paper in a special energy issue of Optics Express, the Optical Society's (OSA) open-access journal, scientists at the University of California, Berkeley ...
Improved spectrometer based on nonlinear optics
New tool allows for higher sensitivity at reduced complexity and cost
14-11-2008
Scientists at Stanford University and Japan's National Institute of Informatics have created a new highly sensitive infrared spectrometer. The device converts light from the infrared part of the spectrum to the visible part, where the availability of superior optical detectors results in ...
Silicon optical fiber made practical
29-10-2008
Scientists at Clemson University for the first time have been able to make a practical optical fiber with a silicon core, according to a new paper published in the current issue of the Optical Society's open-access journal, Optics Express. Led by Professor John Ballato and including fiber ...
Researchers use light to detect Alzheimer's
New technique may help identify ways to predict and prevent deadly disease
18-03-2008
A team of researchers in Bedford, Mass. has developed a way of examining brain tissue with near-infrared light to detect signs of Alzheimer's disease. In the March 15 issue of the journal Optics Letters, published by the Optical Society of America, the team describes how they used optical ...
