摘要
通过强光辐照光电成像系统实验研究, 得到了饱和像元数与入射光强、光学系统参数、像元饱和阈值等参数之间的变化规律, 并利用光学系统点扩展函数(PSF)进行了理论验证。结果表明, 饱和像元主要由衍射效应引起。推导了饱和像元数与入射光强、波长、光学系统参数、像元饱和阈值等参数之间的关系。
Abstract
Based on the experimental research on the electro-optical imaging system induced by intense light, the various rules of the parameters such as saturated pixels, the intensity of incidence, the parameters of the optical system and the saturated threshold of pixels are obtained. And the point spread function (PSF) of the optical system is used to verify theoretically. The result shows that saturated pixels have been made by diffraction effect. The relationships between saturated pixels and the intensity of incidence, wavelength, the parameters of the optical system, the saturated threshold of pixels are derived.
