Noise model of hyperspectral imaging system and influence on radiation sensitivity

Abstract

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.
