高光谱成像系统的应用效果非常依赖仪器获取图像的信噪比。根据高光谱成像系统的设计特点和各种噪声的来源, 建立了时域噪声、空域噪声、空间干扰和光谱混叠等各种噪声模型, 在此基础上详细分析了各种噪声对高光谱成像系统的影响和制约, 结论对提升中国高光谱成像系统的实用性具有重要意义。

The application effect of the hyperspectral imaging system heavily relies on the signal to noise ratio. According to design features of hyperspectral imaging system and source of various noises, various noise models are established like time-domain noise, spatial-domain noise, spatial interference, spectrum superposition and so on and the influence and restriction of various noises on hyperspectral imaging system are analyzed in detail on this basis. The conclusion of this paper plays an important role in promoting the practicability of the hyperspectral imaging system in China.
