Performance improvement of photoacoustic spectroscopy gas detection system

Fast and accurate on-line monitoring and early warning of toxic, harmful, flammable and explosive gases is an important part of ensuring industrial and agricultural production safety and residents' safety. Photoacoustic spectroscopy (PAS) plays an important role in trace gas sensing. Researchers are focusing on improving the performance of PAS-based gas sensors to satisfy different applications. This paper mainly introduces our recent work on improving the performance of photoacoustic spectroscopy gas detection system.
