首先，学习显微镜如何调焦。
介绍了一个基于图像处理的自动调焦系统，该系统由光学显微镜、CCD、力矩电机和齿轮传动机构等组成。
Based on the image processing technology, an auto-focusing system consisted of optical microscope, CCD, moment motor and drive gear etc, was presented.
文中介绍了自动调焦装置的工作原理，并给出了技术指标，这种装置能解决中倍数生物显微镜的自动调焦问题。
The working principle is explained and technical performances are also given. This device is especially useful for microscopes with midmagnifying power.
