| This paper presents detection, identification and quantification of gases using an infrared imaging Fourier-transform: spectrometer. The company Telops has developed an imaging Fourier-transform spectrometer instrument, Hyper-Cam sensor, which is offered as short or long wave infrared sensor. The principle of operation of the spectrometer and the methodology for gases detection, identification and quantification has been shown in the paper, as well as theoretical evaluation of gases detection possibility. The variation of a signal reaching the imaging Fourier-transform spectrometer caused by the presence of a gas has been calculated and compared with the reference signal obtained without the presence of a gas in the imaging Fourier-transform spectrometer field of view. Some result of the detection of various types of gases has been also included in the paper. |
