摘要
介绍了一种基于单片机的利用步进电机控制线阵CCD固态传感器来自动准确对镜头焦面定位的一种新方法 ,系统从根本上克服了人为因素在焦距测量中的影响 ,实现了焦距的自动测量 ,具有一定的实用价值。
A new way to locate focus surface is introduced, the system controls linear CCD sensor applying step motor to Auto locate focus surface accuratly. System surmounts the influence of artificial factor from foundation in focus measuring. The automatic measure of focal distance is realized. This system has certain practical value.
