Paper Abstract

Fluorescence fiber sensors are broadly used to measure temperature, concentration, and pH value etc. The fluorescence sensing systems are based on different principles, namely fluorescence intensity, fluorescence intensity ratio, and fluorescence lifetime. The fluorescence lifetime is an effective parameter for sensing purpose, because it is independent on the intensity of the pumping source and does not need expensive narrow-band filter. An experiment system has been established. Some samples are produced to measured the fluorescence lifetime of temperature characteristic and get the relationship of strain and temperature versus the fluorescence lifetime at the same time. The experiment result was fitted and analyzed. The test results show that the fluorescence lifetime decreased with the increasing of temperature. The change of fluorescence lifetime with the strain is inconspicuous comparing to that with the temperature.
