KYKY2000型数字化扫描电镜的主要特点是引入了图象处理功能。整个系统由一台主计算机控制,部件之间使用数字通讯传递信息,使仪器的自动化程度有了很大的提高,其电器系统的简要框图见附图。图中面板控制是由电镜控制面板上的一些按键和光编码器组成,其与主计算机的键盘一起使得整个系统操作简便,可靠性强。电子光学及放大倍数控制系统主要是由一个Z80微机来控制透镜、对中、消象散器、亮度对比度等各种电源及放大倍数,并完成与主机的通讯任务,使得主机能够对电子光学系统做各种自动控制。编程扫描发生器的核心也是一个Z80微机,它完全由软件程序来产生多种方式下的扫描信
KYKY2000 digital scanning electron microscopy is the introduction of the main features of image processing. The whole system is controlled by a host computer. The components communicate information by digital communication, which greatly improves the degree of automation of the instrument. A brief block diagram of the electrical system is shown in the attached drawings. Panel control by the electron microscope control panel on the number of buttons and optical encoder components, together with the host computer’s keyboard makes the entire system easy to operate, high reliability. Electronic optical and magnification control system is mainly composed of a Z80 microcomputer to control the lens, the disappearance of the diffusers, brightness contrast and other power and magnification, and to complete the task of communication with the host, allowing the host to the electronic optical system Do all kinds of automatic control. Programming scan generator is also a core Z80 microcomputer, which is entirely by the software program to generate a variety of ways to scan letter
