In recent years, remote gas sensing methods have been a heated topic because of their applications in atmosphere pollution detection. Potential pollution gases in the atmosphere are supposed to be sensed, monitored, and dealt with accordingly to meet the requirements of environmental protection. Mid-infrared spectroscopy (MIRS) is a mature technology for matter detection. It utilizes the broadband features of mid-infrared lasers and is versatile enough to be applied in many situations such as molecule detection, biological research, and astronomy science. In this paper, a practicable remote gas sensing method that is based on improved MIRS is introduced and modeled. In addition, the experimental results of the model are analyzed, and the prospects of this method are discussed.
