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.
