一种提高CCD空间分辨力的方法研究
摘要
基于多次移位成像的原理
提出了一种提高红外电荷耦合器件(CCD)空间分辨力的方法。在不改变CCD像元尺寸的前提下
使各相邻像元对应的地面目标进行局部多次采样
提高采样频率
达到将CCD空间分辨力提高多倍的目的。仿真试验显示了其良好的性能。
Abstract
Based on the multi-shift imaging theory
a method for improvement on infrared CCD spatial resolution is proposed.No changing the size of CCD pixel
the sampling frequency is improved through multi-sampling for every pixel.The spatial resolution of CCD is improved.The simulation experiments demonstrate its good performance.
