HIGH SPATIAL RESOLUTION IN DISTRIBUTED TEMPERATURE MEASUREMENT SENSORS

Giovanni Betta, Ainhoa Gaston, Antonio Pietrosanto, Joaquìn Sevilla

Abstract

A fiber optic reflectometric temperature sensor was set up and characterised. Its reduced dimensions render it suitable for monitoring application whenever a high spatial resolution is required. The metrological performance of the first prototype seems very interesting in terms of accuracy and above all, response time. This performance will be further improved by employing a side-polishing technique for sensor realisation and silver mirroring for its reflective part.
