Research On Spectral Imaging Using Of Infrared Imaging System

At first, the article give a brief introduction of the development current situation of the spectral imaging, infrared thermal imager at home and abroad. It elaborates on the theory of blackbody radiation, as well as the composition of the thermal imager, classification, basic principles and so on.Second, based on the blackbody radiation theory, make use of the infrared thermal imager to collect and analysis the thermal images, distill the temperature value of different pixel of the thermal images, use Matlab to deal blackbody radiation emitted curve fitting according with the temperature value of different pixels, and get the values of the degree of radiation emitted at the same wavelength from the different pixels, then make spectral imaging (1μm～10μm) according to the values.At last, do analysis to spectral imaging of different spectral bands; discuss the limitations of using this method to achieve spectral imaging, as the same time, prospect the using of thermal infrared imager for spectral imaging.
