摘要

A fluorescence optical fiber temperature measurement system applied to microwave digestion instrument is designed. The blue LED is adopted as the excitation of a series of light pulses from LED. After having been detected, the signal is amplified by a low noise wide band amplifier firstly. Then every decay curve is digitized. The method of least squares curve fitting is used to make the best exponential fitting curve. Finally, comparing the value of the time constant with the data comparison sheet, the temperature of the sensor can be confirmed.
