Photonics in: Consumer Goods
People in Tokyo like to line up. They line up at 4 a.m. to obtain a box of traditional sweets or the tickets for the last concert of a minor pop singer. Long lines of people even wait for shops to...
Photonics Design & Solutions:
Machine vision users are beginning to consider color imaging an important source of information for quality assurance and part verification. Applications in lumber sorting, food inspection, digital...
Lab and Factory Share Lasers
In the beginning, the development of scientific lasers was stimulated almost entirely by the applications that users could dream up. Over the last three decades, flashlamp-pumped pulsed Nd:YAG laser...
Big Hopes for Small Lasers
The growth in telecommunications, data storage and data processing is driving fiber optic data communications to progress at a breathtaking rate. At the "edge" of the network, outside the dense...
Photonics in: The Laboratory
We asked laboratory managers what features they look for in photonic equipment and what they expect to buy in the next few years. The laboratory market is fragmented, with scientists in different...
Industrial Lasers Make Their Mark
Like TV’s Tim "The Tool Man" Taylor, industrial laser users demand more power from their tools. Higher powers expand the capabilities of the lasers, including their ability to cut and weld...

Infrared Sensor Watches for Black Ice
CANBY, Ore. -- Black ice is a tricky thing. You’re sailing down the freeway because everything looks fine, when suddenly the next curve you maneuver sends you into a spin. Now, an infrared temperature sensor promises to alert drivers to this otherwise invisible road hazard, and help them decide when to slow down or pull off the road. Most temperature-sensing devices detect the ambient air...
IR Exposes Gas-Phase Metal Carbides
Researchers have produced the first direct infrared spectra of the gas-phase metal carbide clusters Ti8C12 and Ti14C13. The vibrational spectra, which reflect the atomic forces that give a molecule...
