定标器

This article introduced a kind of digitized scaler which is maked out by single chip microcomputer and controlled by computer.

本文介绍了一种用PC机作为上位机，单片机作为下位机的数字化定标器。

A microcomputer is used to communicate with the controller of electron probe to control the spectrometers and the sample stages as well as the scalers. Data of X-ray intensity are acquisited when the sample stages are scanning in a certain step and time period. X-ray images were formed and shown in colors or in 3 dimensions, and have no distortion at low magnification. Hidden zonate phenomena of a picrite were found.

摘 要：用微型计算机与电子探针控制机通讯，实现对各道波谱仪和样品台的实时控制，以及对各道定标器的数据采集；在选定的样品区域上设定采样步长和时间，边移动样品台边采集各道X射线强度；用伪彩色、三维视图和内插放大等方式显示图像，解决了低倍X射线像失真问题，观察到了辉石的隐环带等现象。
