Based on the electronic focus technology development of state-of-the-art,the paper suggested a complete apparatus scheme of auto-focus based on SSPD(self-scanned photodiode array)and 8098 single chip processor,giving out a focus criterion algorithm based on image high frequency statistics.
在介绍与分析了国内外电子调焦系统的技术发展与现状的基础上 ,提出了一种基于 SSPD(自扫描光电二极管列阵 )与 80 98单片微处理器自动调焦的整体技术方案 ,给出了基于图像高频成分统计的聚焦判识算法 ,在此基础上实现了反射式与透射式光学显微镜的自动调焦 ,同时对系统的可靠性有关的其它相关问题如光源稳定性、步进电机驱动等问题也进行了讨
