Simple distributed fiber sensor based on Brillouin gain spectrum analysis.
A novel configuration of a distributed fiber sensor by Brillouin gain analysis has been developed for temperature and strain monitoring. It uses a single laser source, and the required light signals are all generated with an electro-optic modulator, resulting in high stability and excellent reliability of the measuring setup. Measurement of the induced strain in a wound fiber is presented as a ...
متن کامل32-km distributed temperature sensor based on Brillouin loss in an optical fiber.
Among the hierarchy of sensors, the distributed fiberoptic temperature sensor is unique, as it offers continuous sensing over tens of kilometers with good temperature accuracy and high spatial resolution. Distributed temperature sensors (DTS's) that use Raman scattering as the sensing mechanism have already been reported.`-4 More recently, the variation with temperature of the Stokes frequency ...
متن کاملCombined distributed temperature and strain sensor based on Brillouin loss in an optical fiber.
Long-range distributed optical fiber sensors1-5 exploit the interaction between laser light and the fundamental energy transport mechanisms in the scattering medium. Here we report on the use of Brillouin loss for a combined distributed temperature and strain sensor. Brillouin lossbased distributed sensors exploit the Brillouin interaction between pulsed and cw optical beams counterpropagating ...
متن کاملPulse shape effects on the measurement of Temperature using a Brillouin based Optical fiber sensor
Distributed fiber sensing based on Brillouin gain scattering (BGS) principle is a useful way to develop devices capable to measure temperature or/and strain in optical fibers. New effects or technologies that could achieve a larger distance and/or a better spatial resolution are a topic of special interest in this fiber sensing area. The influence of the probe-pulse shape in the interaction bet...
متن کاملAn Optical-Fiber-Based Airborne Particle Sensor
A new optical-fiber-based airborne particle counter is reported. Unlike traditional light-scatter-based techniques, the particle is detected through the drop in optical fiber coupling efficiency as the particle disrupts the electromagnetic mode of the optical beam. The system is simple, substantially smaller than traditional systems, and does not require high power laser input. This makes it at...
