摘要

设计了一种基于可调法布里—珀罗（F-P）腔的气体体积分数测量方案:引入标准光栅作为参考

解决了F-P腔选频特性受温度影响的难题;利用谐波检测的方法提高了测量的灵敏度;可以用于多种气体体积分数的检测;最后

利用乙炔气体进行了实验验证

取得了较好的效果。

Abstract

A scheme is designed to measure the gas volume fraction based on tunable Fabry-Perot（F-P） cavity.Standard grating as reference is imported to solve the problem that the characteristic of choosing frequency of F-P cavity is influenced by temperature;harmonic detection is used to improve the measuring sensitivity;volume fraction of different gases can be detected;lastly

an experiment with C2H2 is designed to validate the scheme

and has a good result.
