Staff Report
Cameras, lasers and instrumentation help law-enforcement officers track down evidence and people in criminal investigations. Patrick Baxter, serving time in New York for car theft, was indicted last November on charges in three murder cases, one of them 13 years old. In August, Roy Criner was pardoned after serving a decade in a Texas jail for rape. In a recent New Mexico murder case, "invisible"...
Clever Cameras Do More Than See
A picture may be worth a thousand words, but sometimes what’s needed are just a few: good, bad, accept, reject. In manufacturing, product assessment is often based on visual data. A human then...
Fast Coatings for DWDM Filters
Current and forecast market requirements for dense wavelength division multiplexing (DWDM) filters are driving the need for ever-increasing production throughput. Manufacturers are calling for larger...
Have You Hugged Your Fiber Today?
The information explosion ignited by the Internet has created an insatiable appetite for bandwidth. To appease the bandwidth hunger, most telecommunications operators are pushed to increase the...
Ball vs. Gradient Index Lenses
In modern communications systems, micro-optic components couple light between fibers, from laser diodes to fibers and from fibers to detectors. They also collimate light from fibers i thin-film...
The Big Trade-Off
Semiconductor lasers are very small (about the size of a grain of salt), very efficient electrically powered sources of coherent light. In the mid-1980s, their availability in large quantities and...
Untangling the Wavelength Web
The growth of the Internet is fundamentally reshaping communications and proving that too much bandwidth is not enough. According to communications research firm RHK Inc. of South San Francisco, the...

Mini Interferometer Analyzes Tiny Samples
LUBBOCK, Texas -- As biochemical analyses become more critical to the understanding and treatment of disease, the need for rapid and inexpensive measurement techniques continues to grow. Miniaturization promises to deliver both for small-volume samples, but significant issues must be addressed to ensure accuracy. A new method based on backscatter interferometry may enable researchers to analyze...
Laser Pulses Create Antimatter
