0 引言 光功率推动传感器是光纤传感器中一个崭新分支,是利用电传感器的成熟技术和光纤传感器的独特优势形成的近于全光型新型传感器。八十年代中期国外已开始致力于此项研究。我们研制的光功率测温仪采用R_k/PWM/PPM调制技术实现探测器的微功耗,一根光纤既作信号通路又作功率通路,单片微机对测量信号进行处理、运算和建模,探测器相 0 Introduction Optical power to promote the sensor is a new branch of the optical fiber sensor is the use of electrical sensors mature technology and the unique advantages of optical sensors to form nearly all-optical new sensor. Mid-eighties abroad has begun to devote themselves to this study. The optical power thermometer we developed uses R_k / PWM / PPM modulation technology to realize the micro-power consumption of the detector. One optical fiber serves as the signal path and the power path, and the single-chip microcomputer processes, calculates and models the measurement signal, Detector phase
