推导出了静态干涉成像光谱仪的探测器阵列采样空间调制干涉图的实际数学表达式,由此进一步推导出了含像元光敏宽度的复原光谱幅值的一般表达式。分析结果表明,当像元间距一定时,光敏宽度对复原光谱幅值存在影响。对于确定的光敏宽度,随着波数的变长,复原光谱幅值所受到的影响逐渐增大;对于确定的波数,随着光敏宽度的变宽,复原光谱幅值所受到的影响逐步增大。
The actual mathematical expression of the interferogram of the detector array sample space in the static interference imaging spectrometer is deduced, and the general expression of the amplitude of the reconstructed spectrum with the photosensitive width of the pixel is deduced. The analysis results show that when the pixel spacing is constant, the photosensitive width has an impact on the recovery spectral amplitude. For a certain photosensitivity width, as the wave number increases, the amplitude of the restored spectrum gradually increases. For the determined wave number, the amplitude of the restored spectrum gradually increases with the increase of the photosensitivity width.
