Improving the Picture of Food Production
If you are what you eat, then it might be good for food to get the right – and therefore light – touch. Photonics-driven improvements in food inspection and handling could result in fewer illnesses, less waste, cheaper prices and better quality. There is clearly a need for better inspection. According to the Centers for Disease Control and Prevention, food-borne illnesses hospitalize...
Choosing a Material for Use in the Infrared

Editorial
Supply and Demand
I first learned of recent rather dramatic price hikes in cerium slurry when a reader with cause for worry called me in late September. Cerium is one of the 17 rare-earth elements (REEs) – numbered 57 through 71 on the periodic table, plus scandium (21) and yttrium (39) – many of which are critical in the manufacture of products at the very heart of our high-tech world, products for...

Tiny laser: Big challenge
Since the invention of lasers 50 years ago, some scientists have worked to make the new versions bigger and more powerful, while others have been in pursuit of smaller and more efficient models. Now, a group of scientists at Harvard University and Georgia Institute of Technology in Atlanta believe it has taken an important step toward creating an ultrasmall laser with what it claims is the...
New color filter could spell “grate” success for future displays
Scientists are seeking to commercialize a new type of color filter that they claim could be a step toward more efficient, smaller and higher definition display screens. The filter can be integrated...
Tiny antennas squeeze light for better biosensors
A new class of biosensors could be at hand, according to Northwestern University researchers. They constructed composite metal-dielectric-metal nanoantennas on the facet of a quantum cascade laser,...
Carbon nanotube forest enhances NIST detector
A new ultradark detector that reflects almost no light could lead to vastly improved laser power measurement. Thermal detectors measure laser power by converting photons into heat, and National...

Uncooled IR cameras and detectors: Costing less, scaling up
Prices of uncooled IR detectors and cameras are falling, thanks to numerous technological and business developments. Driven by this cost reduction, the market volume for thermography and IR vision will triple by 2015, according to Yole Développement. The volume of uncooled IR cameras sold is expected to rise to more than 700,000 units in 2015, up from 200,000 in 2010, with an annual...

Will LEDs lead to a greener world? Maybe
Conventional wisdom says that replacing the power-hungry incandescent bulb with compact fluorescent bulbs or LEDs that are more efficient will lead to a reduced demand for electric power and the eventual shuttering of polluting power plants, making the world greener. But scientists at Sandia National Laboratories in Albuquerque, N.M., recently predicted that the increased use of LEDs will...
