摘要/Abstract

摘要：

基于帧转移型面阵CCD的成像原理，探讨了光电转换、电荷转移和电荷检测三个成像阶段存在的一些关键性问题，如像元响应的不一致性、相机抖动、电荷转移效率、帧转移模糊等，建立了相应的数学模型，并利用VC++6.0开发平台搭建了一整套CCD成像仿真系统。最后利用实验的方法，通过改变转移效率、曝光时间等CCD成像参数，分析比较了仿真结果。实验表明，该数学模型与面阵CCD器件成像过程较为吻合，仿真系统准确度较高。

关键词: 面阵CCD, 成像仿真系统, 电荷转移效率, 帧转移模糊

Abstract:

Based on the imaging principle of frame transfer CCD sensor , some key problems during photoelectric coversion, charge transferring and electron detecting were discussed, such as pixel response non-uniformity, camera shaking, charge transfer efficiency, the frame transfer smear, etc. The corresponding mathematical model was established. The simulation system was designed based on the platform of VC++ 6.0. At last, based on the experimental method, by changing the CCD parameters, such as the transfer efficiency, exposure time, etc, the simulation results were analyzed. Experimental results showed the validity of simulation system.

Key words: array CCD, imaging simulation system, charge transfer efficiency, frame transfer smear
