基于红外光声光谱的气体检测系统设计
摘要
随着工业现代化的发展
环境变化日益复杂
而人民的环境健康意识也在不断提高。在这种情况下
传统的气体检测系统已不能满足要求
有待开发一种高灵敏度、高分辨率的新型实时气体检测系统。从气体分子红外光谱理论出发
在对当前各种气体检测方法进行分析比较的基础上
设计了一种基于光声光谱技术的气体检测系统。实验证明:该系统可有效进行CO

Abstract
In recent years
with development of modern industry
increasing complexity of environmental change
and people’ s awareness of environmental health is improving.In this case
conventional gas detecting system can not meet requirements
pending the development of a high sensitivity
high resolution new type realtime gas detecting system.From gas molecules IR spectrum theory
and on the basis of comparison of current variety of gas detection method
study on a gas detecting system based on photoacoustic spectrum(PAS) technology.Experiment verifies that this system can effectively carry out CO
