SENSORS WEEKLY

Digital Data Acquisition and Analysis
A Digital data acquisition/recording system is the fundamental component of almost every experiment performed today. The success of the experiment is entirely dependent on the capabilities of the system and it is almost universally assumed that it will provide the correct answer. Unfortunately, life is not so simple.

A Novel Fiber-Optic Fluid Interface SensorA Novel Fiber-Optic Fluid Interface Sensor

The article presents the proof-of-principle of a new sensor capable of detecting the position of the interface between two fluids.

Fiber Optics For Environmental Sensing

A staple of the oil industry, distributed temperature sensing (DTS)—capable of measuring temperature along a length of fiber-optic cable—is finding utility in environmental monitoring, helping researchers to tease out the hydrology of streams, air flow in valleys, and health of glaciers.

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.
