AUTUM C. PYLANT, NEWS EDITOR, [email protected]GRENOBLE, France, Nov. 26, 2018 — Events such as the Port of Rizhao gas plant explosion in China that killed 173 people and injured hundreds of others in 2015; the explosion at the U.S.’s third largest refinery in Texas City, Texas, in 2005; and the Buncefield oil storage explosion in Hertfordshire, England, in 2005 can devastate communities, leaving a mark for generations. By using autonomous patrolling robots, photonic integrated circuits (PICs), and photoacoustic gas sensors, European researchers are using light and sound together to prevent similar mishaps.

This article explores the many ways to achieve that goal.Just as an electronic connector provides a pluggable connection between electronic circuits, a fiber optic connector provides an optical one. The goal is joining a fiber to a transmitter, receiver or...Photonics HandbookPhotomultipliers: Low-Light, High-Speed Specialists: Rapid detection of light calls for a sensitive detector and electronics that do not introduce additional signal noise. In fact, for very rapid detection, detector shot noise does not determine the signal-to-noise ratio. Instead, the amplifier has the most impact, which is why many designers have selected a photomultiplier tube for the high-speed or low-light-level detection of photons.The applications where rapid detection of light is a must are many. They include a wide variety: semiconductor inspection, gene sequencing, oil well logging and high-energy physics. The reasons for...Photonics HandbookRadiometry: A Simplified Description of Light Measurement: Radiometry involves measuring and predicting levels of optical radiation. This article removes some of the confusion surrounding this often complex technology.Radiometry involves several activities. The two most common are the description and measurement of optical radiation, and, starting with the knowledge of some aspects of optical radiation at one...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 HandbookWHITEPAPERSOrdering Options: What Does Your Camera Need?This paper covers how to best optimize a camera order to improve camera performance.
