Study On Chemical Agents Infrared Spectral Imaging Technology Based On Testing Technology

Infrared spectra of material molecules are selective radiation and absorption,which have the characteristics of the same height as the fingerprint,and become a kind of important analysis tool in determining the existence of acertainregion.Infrared spectrum analysis and infrared imaging technology,infrared spectroscopy can be used to determine the characteristics of a specific compound,and infrared imaging technology can let the human eye can’t see the infrared radiation distribution of the state become visible images;this combination can be directly observed in the visual image,determine the existence of this particular compound,and its precise location.With the development of infrared detector and digital signal processing technology,Fourier transform infrared spectroscopy(FTIR)combined with,and adopt the modern pattern recognition and signal processing technology makes chemical agents spectral remote sensing technology has entered a practical stage.In this paper,the composition of the CHIPED-1 long wave infrared imaging system,the spectral data processing technique are introduced.Introduced the infrared spectral imager spectral calibration,radiometric calibration technology,discussed the principle of the brightness temperature method for the detection of chemical warfare agents.Spectrum detection of chemical agents,experimental vzilidation study,obtains the related experimental results,provide the beneficial reference for the next step in CHIPED-1 longwave infrared spectral imaging system improvement design.
