摘要
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。
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.The function of auto-focus of both reflected and transparent optical microscope was realized.Meanwhile some corresponding problems such as stability of light source,step motor driving etc.were also discussed,which greatly improved the accuracy and reliability of the system.
