光声光谱技术进行气体检测研究综述

摘要

光声光谱技术是近几年发展起来的一种以光声效应为基础的新型光谱分析检测技术。基于其极高的检测灵敏度,已成为一种快速、安全、可靠、有效的微量气体检测技术手段。文章对光声光谱气体检测的基本原理及其在气体检测研究中的最新进展进行了概括和总结,并对其在乙烯等果蔬气体检测中的研究前景进行了分析。%Photoacoustic spectroscopy is a new-style measurement technique for spectrum analysis based on photoacoustic effect. Qwing to the high sensitivity, the technique of photoacoustic spectroscopy has been a fast and effective measurement technique for trace gas detection.In this paper, the principle of photoacoustic spectroscopy and the recent research progresses gas detection are introduced and illustrated. And the research prospect is anaysized for C2H4 and other trace gas of garden stuff.
