Despite the widespread use of luminescence lifetimes in physical measurements, there seems to be no consensus on the best method for lifetime determination. Researchers in this field split into two ...

High time-resolution monitoring of nitrogen dioxide (NO2) is of great importance for studying the formation mechanism of aerosols and improving air quality. Based on the Griess–Saltzman (GS) reaction, ...

A micro-displacement sensing head based on two aligned cleaved fibers inserted into an optical fiber ring and interrogated by an optical time-domain reflectometry is presented. The sensor ...

Do you need to calculate time-of-flight? Do you need to calculate absolute time? Then you'll probably need a time-to-digital ...

The Portable Optical Time Domain Reflectometer (OTDR) is a compact and versatile instrument used to analyze fiber optic cables by measuring the time and intensity of light reflections. This device ...

A low-coherence OTDR that can control spatial resolution is demonstrated through the use of a new light source consisting of a superluminescent diode (SLD), an AR-coated LD booster amplifier, and two ...
