Abstract

Based on the working mechanism and characteristics of spaceborne hyperspectral Fourier transform infrared spectrometer, the computer and software were used as data acquisition and processing tools in this paper to study and simulate the various processes in photoelectric information processing of spectrometer. Analytical models including functional modules such as interference signal generation, effective signal detection, spectral data inversion and instrument error correction was established, then a visualization software system was developed. Finally, the accuracy of the model was calculated and optimized with experiments, the verification results show that this resolving system can process the interference data with high spectral resolution non-destructively, significantly improve the smoothness of the restored spectrum without distortion, and the measured spectral resolution of an instrument is better than 0.03cm^-1 . This digital model could provide useful support for the design and parameter optimization of the aerospace Fourier transform infrared spectrometer.
