Linear Avalanche Photodiodes Enable Single Photon Sensors

Single photons are elementary particles that are arguably the most tangible, yet some of the most difficult to detect and characterize as single entities. Techniques to count single photons require optical detectors with linear operation, high gain, wide bandwidth and low noise. This article will describe a variety of approaches to detect and count single photons, the key measurement metrics, and potential applications of single photon sensors.

Future Networks

The next generation of networks will move beyond disconnected device-specific networks and systems and toward a distributed infrastructure, with intelligent functions residing across the entire network, from its edge to its core.

On-Site Trace Chemical Detection, Part 1: Understanding Ion Mobility and Differential Ion Mobility Spectroscopy

The first installment of this two-part series discusses ion mobility spectroscopy (IMS), the leading contender for fast and reliable detection of trace chemicals, and differential ion mobility spectroscopy (DMS), a related technology that provides faster, smaller and more sensitive sensors capable of detecting chemicals in environments with greater concentrations of interfering substances.

Mixing Multiple Wireless Technologies

With the variety of wireless technologies available, outfitting an industrial or commercial environment for wireless communications may involve mixing and matching technologies to find the optimal solution. Here are the issues to consider to make your mix a successful one.
