在电视显微镜上安装一组步进电机能实现自动粗调焦和等距移动标本。用8031单片机应用系统控制步进电机的运转，在功率放大器中选用IRF530场效应管以提高系统的性能和可靠性。这种显微镜与微机组合，构成普及型显微图象处理系统的硬件基础。
Installing a set of stepper motors on the TV microscope enables automatic coarse focusing and equidistant movement of the specimen. The 8031 microcontroller application system is used to control the operation of the stepper motor. The IRF530 field effect transistor is used in the power amplifier to improve the system performance and reliability. This combination of a microscope and a microcomputer constitutes the hardware basis for a popular microscopic image processing system.
