Fiber Optic Temperature Sensor Design based on Fluorescent Lifetime
The temperature is measured by the fluorescent lifetime of fluorescent material. In this work, the analog switch was controlled by single chip to trigger exciting light emission of LED. In order to measure the fluorescent lifetime, pho- toelectric detector, amplifier and active power filter were used. The modulation frequency of fluorescent signal was de- tected by phase locking detection method. Therefore, the temperature measurement in the range of 0°C�450°C was real- ized. This sensor has advantages such as high accuracy, strong anti-electromagnetic interference and non-contact meas- urement.
