Abstract :
A portable, fluorescence-based fiber-optic thermometer for use in the 30-50 degrees C range has been constructed using inexpensive solid state electronic and optoelectronic components. A novel measurement scheme allows greater noise discrimination to be achieved with such low bandwidth components. The system is described and discussed, and results of its calibration are reported.
