[Passive remote measurement of flame infrared image by a FTIR scanning imaging system].
The present paper introduced a FTIR scanning imaging system. This system is based on the combination of a FTIR spectrometer and a scanning mirror. So it has the advantage of FTIR spectrometer: non-contact, real-time, celerity, nicety and high sensitivity. Through scanning mirror, the authors can obtain the space information of targets. The authors used this system to measure the flames infrared emission spectra of three alcohol burners at a flat roof in our laboratory. According to Planck's law, the authors calculated the relative temperature of from each spectrum. These temperature data formed an array. The authors used matlab software to plot the infrared images of target and contrasted them with video image. They were consistent with each other very well. This experiment allowed us to obtain the temperature distribution of three alcohol burners' flames, and provide identification, visualization, and quantification of pollutant clouds.
