Anne L. Fischer, Senior Editor, [email protected]Driving down the highway, zinging by countless streetlights, we rarely consider the technology behind them, their cost or how much energy they consume. Not much has changed in streetlights in decades. But change is afoot, as lighting designers test more energy-efficient, lower-maintenance and longer-lasting lighting sources. It’s enough to make you slow down and take notice. In 2005, the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute (RPI) in Troy, N.Y., surveyed utilities and cities and found that high-pressure sodium lamps were used in 83 percent of streetlights,...Read full articleRelated content from Photonics MediaARTICLESMethod Makes Generic Polymers LuminescentA Hokkaido University research team has developed a method to give luminescent properties to generic polymers, potentially transforming existing commodity polymers into more valuable functional...Photonics Spectra September 2021 IssueForeign Atoms Help Monolayer Graphene Overcome LimitationsResearchers at Daegu Gyeongbuk Institute of Science and Technology (DGIST) have introduced a simple methodology that enables the fine control over the integration of foreign atoms with graphene.

Digital ultraviolet imaging is becoming increasingly affordable and lends itself to a number of interesting applications that have been largely overlooked, and digital sensors are available that span the UV spectrum from 200 to 400 nm.Reflected-ultraviolet imaging is a rather mysterious area of the imaging field. There is relatively little actual UV imagery to be found on the Internet or in the literature compared to near-infrared...Photonics HandbookOTDRs: Finding the Weak Spots in Fiber Links: The optical time-domain reflectometer (OTDR) is used to characterize a fiber optic span. It performs single-ended tests and can calculate fiber attenuation and uniformity and splice and connector losses. It can also locate breaks and determine fiber length. Its ability to locate and measure reflectance and loss makes it the troubleshooting and fault locating equipment of choice. New generation OTDRs include advanced functions such as macrobend location, active-fiber testing and automatic trace acquisition.An optical time-domain reflectometer sends short pulses of light into a fiber and measures its reflections as a function of time. The delay of these reflections to the detector as well as their...Photonics HandbookRadiometry: A Simplified Description of Light Measurement: Radiometry involves measuring and predicting levels of optical radiation.
