| 摘 要： | 提出了一种通过波长扫描来检测C2H4 和H2S混合气体的体积分数的新方法。采用超发光二极管作为光源, 2个检测通道共用 1根光纤,通过光源调制实现气体的体积分数的谐波检测技术。该系统最小可探测气体的体积分数约为 10-4, 移植性好,对大多数气体均适用。

| Abstract: | Based on the laser scanning,a new method is used to detect the mixed gas volume fraction of C_2H_4 and H_2S.Super luminescent diode is used as a light source and two detecting channels share a segment fiber,and light source modulation harmonic measurement is presented for detecting the gas volume fraction.The minimum detectable volume fraction is about 10~(-4),the transplant property is good,and the detection system is applicable for a great deal of gases. |
