Optic-fiber Sensor Based on Fluorescence Mechanism

A kind of fluorescence optic-fiber thermometer is devised based on the solid-state ruby fluorescence material. The characteristic of fluorescence material absorption and emission is analysised, and the optic-fiber temperature measurement probe based on ruby is developed. This system is particularly adapt to the temperature measurement in the rang of 20°C to 600°C. During the cause of experimentation, this temperature measurement method is proved to be effective and useful for its highly resolution and precision.
