Abstract
The development and calibration of a visible LED-pumped, photoluminescent optical-fiber sensor to measure temperature using the crystal alexandrite is reported. Utilizing the dependence of the fluorescent decay time on temperature, this instrument is accurate to +or-1 degrees C over a range 20-150 degrees C, with a response time of 1 s.
