Development of a test software for the modulated transfer function of ccd camera
Ccd相机调制传递函数测试软件的研制
Through describing the space sampling process of ccd , the composing factors of modulate transfer function ( mtf ) of ccd integral sampling process are analyzed . meanwhile , an effective method to analyze the mtf of discrete sampling image system is put forward and is used to analyze and compare mtfs of sub - pixel image system and singlechip ccd system . as a result , definitions of ccd optical transfer function ( otf ) and optical mtf are presented and effective methods to measure ccd mtf are brought forward
本文通过对ccd器件空间采样过程的描述，详细分析了ccd积分采样过程调制传递函数的构成要素，提出了分析离散采样成像系统调制传递函数的有效方法，并用该方法分析比较了亚像元成像系统与单片ccd系统的mtf ，给出了ccd器件光学传递函数（ otf ）和光学调制传递函数（ mtf ）的定义，提出了检测ccd调制传递函数有效方法，采用几种不同测量方法测定了tdiccd的调制传递函数，并进行了比较分析。
