【摘要】 分析大感光像素特种 CCD 的工艺特点及对系统整体性能参数的影响。提出满势阱光电子数与 CCD 阱面积 A 和阱深 W 的积有关,CCD 分辨间隔取决于光电子统计涨落,大像素提高了 CCD 感光灵敏度和动态范围,对工艺定位要求低,可单件或少量生产,适合我国现有人员、技术、设备和资本经济实力。用 DSP+CPLD、FPGA 器件和 VI 软件制作控制器,强化系统整体配置；寻找各行各业需要、技术对路的特种 CCD 开展研发,实行定单生产,滚动积累开发,走差异化发展道路, 是发展我国 IT 技术产品的策略。更多还原

【Abstract】 The technology characters and its influence on system performance with large sensitive elements on special CCD were analysed.It is concerned that the full well photoelectron number is relatied to the CCD well area A multiplied to its max potential W.The photoelectron fluctuation determines the distinguish space.It has high dynamic range and is not exigent technique and an chor point to large element,even makes in single or less ones.It adapts to our technicians and techniques,equipments,technologies,capital and marketing.It makes up of the controllers by programmable devices DSP+CPLD,FPGA and Ⅵ software,configures the system better.De- veloping special CCD is an important strategy for China IT:finding trade demands,adapting to our technology,and ordering for goods,scrolling and capitaling amassment,developing CCD in diversity.更多还原
