Abstract

FTIR imaging spectrometer has significant meaning in the fields like industrial plume emission monitoring and public security monitoring. In this paper, a LWIR FTIR imaging spectrometer is applied to realize the field gas identification experiment. First, the structure and design of this spectrometer is indicated and discussed. Based on the algorithms research, the related gas identification software is developed. To verify this design, both lab and field experiments are realized. The lab experiment is applied to verify the spectral identification algorithm. The field trial is applied to analyze the gas components, and the results show that this spectrometer can realize the gas elements identification in real time.
