Paper Abstract

A fiber optic thermometric device, which allows to control 19 measuring points, is presented. It utilizes a single electro-optical unit, and an electro-mechanical optical scanner to address the sensor array. Each sensor is intensity modulated type, and utilizes as transducer a differential absorption thermochromic solution, working in the 5°-75°C temperature range. A self-focusing probe is adopted, which presents low intrinsic loss so to achieve high signal-to-noise-ratio.
