Abstract:

A Fourier transform infrared spectrometer is developed for atmospheric composition monitoring. The design and implement of the data acquisition system is introduced. It achieves equal interval sampling of interferogram based on the HeNe laser feedback and control system and a high precision digitizer. It also develops a data acquisition and processing software. Experiments results  indicate that the spectrum resolution can up to 1 cm-1. The system is suitable for the monitoring of atmospheric multi-component.

Key words: Fourier transform infrared spectrometer, data acquisition system, atmospheric multi-component monitoring
