Abstract

Many sources of spectrometer system noise are introduced, which will be superimposed on the interference data. In this paper, the statistical properties of noise are analyzed, and Gaussian models are established by extracting features from the actual collected interferometric data. For 30-degree and 35-degree target radiation sources, the same sets of interferometric data are collected, and the histogram of noise is established and the curve is fitted to match the corresponding Gaussian model. The ideal interference fringe is simulated for the studied spectrometer object, and the effect of Gaussian noise on the interference fringe is analyzed, and the experiments prove that the effect of the noise-added interference fringe is close to that of the measured interference fringe.
