CCD摆动提高摄象机性能的研究

STUDY ON RAISING PERFORMANCE OF CCD CAMERA

本文提出用摆动方法提高CCD摄象机二维空间分辨率的因素及可能达到最大分辨极限。本文还描述了自行设计的实现水平、垂直分辨率各提高一倍的悬臂型压电双晶片微摆动机构;并且详述了水平和垂直分辨率各提高一倍的信号处理方法及产生与现有制式相兼容的高清晰图像信号的再生过程,分析了提高二维清晰度的图象信号系统。

This paper presents the principle to inhance the spatial 2-D resolution of CCD camera by means of Swing of the imager and analyses the factors effecting on its spacial 2-D resolution and the possibly available limitation of maximum resolution. The paper also reports on image signal processing for 2-D high definition picture and the hanging-up piezoelectric bimorph construct designed to improve both horizontal and vertical resolution respectively by one time. The regenerated signal can be Compatible with current TV mode.
