提出用调制传递函数 MTF 评价 CCD 像感器成像质量的方法,给出了计算 CCD 像感器调制传递函数 MTF 的公式,并着重分析了 CCD 像感器的离散性对成像质量的影响。
A method to evaluate the image quality of CCD image sensor by MTF is proposed. The formula for calculating the MTF of CCD image sensor modulation transfer function is given. The influence of the discreteness of CCD image sensor on image quality is analyzed emphatically.
