摘要
介绍了红外成像系统的噪声模型、测量方法和基于实测数据的噪声仿真法。通过分析二代红外成像和一代红外系统的不同特性,导出了更适合二代红外成像系统的三维噪声模型。就三维噪声各个分量表现方式进行了分析,给出了影响噪声分量的原因。结合噪声模型给出了红外成像系统噪声测量方法;最后进行了试验,给出了实验结果,并对模型结合实测数据用于红外图像噪声仿真进行了尝试,并在某试验中得到了初步应用。
In this paper, the noise model, measuring method and method of noise simulation based on measured data are discussed. The differences between first and second generation infrared imaging system are analyzed. The 3-D noise model is introduced ,which is used to analyze the noise of the infrared imaging system. Every component is analyzed in detail. At last, the result of experiment is showed. The noise simulation method of combining noise model with measured data is attempted. It have been preliminarily applied in an experiment.
