Distributed temperature-change sensor based on Rayleigh backscattering in an optical fiber.
A frequency-modulated continuous-wave technique is used to detect the presence of frequency shifts in the Rayleigh-backscattered light in a single-mode optical fiber as a result of a changing temperature. The system is able to detect a rate of temperature change of 0.014 K/s, when a 20-cm length of fiber is heated. The system is also able to demonstrate a spatial resolution of better than 15 cm.
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 کاملA Polymer Optical Fiber Temperature Sensor Based on Material Features
This paper presents a polymer optical fiber (POF)-based temperature sensor. The operation principle of the sensor is the variation in the POF mechanical properties with the temperature variation. Such mechanical property variation leads to a variation in the POF output power when a constant stress is applied to the fiber due to the stress-optical effect. The fiber mechanical properties are char...
متن کاملDistributed optical fiber temperature sensor using only anti-Stokes Raman scattering light in a loop configuration
In this paper we demonstrate distributed Raman temperature sensing (RDTS) in a loop scheme employing anti-Stokes light intensity only. Using a single-channel receiver and anti-Stokes traces measured in loop configuration, we implement RDTS with inherent compensation of fiber wavelength-dependent losses, as well as local external perturbations. Experimental results show a signal-to-noise ratio e...
