报告摘要:
Gas sensing technologies are essential in environmental monitoring, industrial processes, and medical diagnostics. Infrared Absorption Spectroscopy, a non-invasive analytical technique, plays an important role in gas detection due to its selectivity, sensitivity and responsiveness. In this talk, I will present our work on the development and application of gas sensing systems based on several infrared absorption spectroscopy techniques, including Tunable Diode Laser Absorption Spectroscopy (TDLAS), Cavity-Enhanced Absorption Spectroscopy (CEAS), Photoacoustic Spectroscopy (PAS) and Quartz-Enhanced Photoacoustic Spectroscopy (QEPAS). The discussion will cover the principles, advantages, and limitations of each technique, as well as their implementation in detecting trace gases in different environments. I will also provide an outlook on our research and ongoing efforts to enhance the performance and applicability of gas sensing systems.
