摘要 : 介绍了一种傅里叶变换红外光谱仪扫描成像系统,并用该系统测量了放在平台上的3盏普通实验用酒精灯的火焰红外发射谱,选择位于大气窗口内的波数为900~1 000 cm-1 波段,利用普朗克定律,反演出了每条光谱对应的相对温度。实验中每一个光谱对应一个扫描位置即像素点,把这些温度数据通过Matlab软件绘制出了扫描范围内的红外图像。将红外图像叠加在视频图像之上,两者吻合得非常好,清楚地显示了3个火焰的位置。
关键词 :傅里叶变换红外光谱;扫描成像;红外
Abstract :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.
Key words :FTIR;Scanning imaging;Infrared
