Analysis for Signal-to-noise Ratio of Imaging Fourier Transform Spectrometer
成像干涉光谱仪信噪比分析

The general expression about \%SNR\% of Spatially Modulated Imaging Fourier Transform Spectrometer is deduced in detail, and Sagnac type Imaging Fourier Transform Spectrometer is chosen as analysis model. The relationship between affection factors and \%SNR\% is analyzed and corresponding conclusion is obtained.
