摘要：

Long-wave infrared (LWIR) spectral imaging technology has broad application prospects in mineral detection and identification of hazardous chemicals. Five kinds of common interference spectral imagers, such as two-sided Sagnac type, three-sided Sagnac type, static Michelson type, swing arm Michelson type and variable gap Fabry-Perot (F-P) type, are analyzed for the miniaturization and multi-platform application of LWIR spectral imaging technology. The advantages and disadvantages of these imagers are analyzed from the aspects of volume, stability, accuracy requirements, and optical system complexity. A prototype of variable gap F-P spectral imager was developed. The rearrangement, apodization, Fourier transform, spectral radiation calibration and other processing methods are used to accurately invert the target spectrum. The chemical DMMP was tested using the prototype imager, and the test result is consistent with that of MR170 high precision spectrometer. © 2019, Editorial Board of Acta Armamentarii.
