A moving mirror driving system of FT-IR spectrometer for atmospheric analysis was developed. It uses a tilt-compensated interferometer, a He-Ne laser reference interference system, and a driving system based on microcontroller with the control mechanism of adaptive adjustment Fuzzy-PI. The structure is simple and easy alignment. The controller is robust and high precision. It can be used in many applications of atmospheric analysis, such as open path or solar occultation flux FT-IR methods.

This paper describes a long path Fourier transform infrared spectroscopy system which is used to analyze ambient gas. Some VOCs (C2H2, C2H4) are measured with this system in laboratory. As different VOCs has unique infrared absorbing spectrum, we retrieve VOCs concentration based on the nonlinear least square algorithm. The result shows that the system is stable and rapid. The retrieved concentrations are very close to real value. The system can used to monitor and research VOCs in ambient gas.
