摘　　要：介绍了几类化学量光纤传感器的简单原理。用国产元件建立了一个测量大气中甲烷气体浓度的实验装置,该装置的测量灵敏度约为7000ppm,是甲烷气体在大气中最低爆炸极限的13％。The principles of several kinds of chemical optical fiber sensors are presented. An all optical network system employing low-loss optical fiber link for continuous and remote sensing of CH_4 gas concentration has been developed. Based on the present experiments, the detection limit of CH_4 in air comes up to 7000 ppm, i. e. 13% of the lower explosion limit of CH_4.
