摘要
本文介绍测量高分辨率显示管分辨率的新装置．它由ＣＣＤ光电传感头将光信号转换成电信号，再由微机进行处理，实现自动测量．本装置测试精度高，测量速度快，为研究和生产高分辨率ＣＲＴ和偏转线圈提供了一种先进的测试手段．
This article introduces an automatic measuuring set fox detection the resolution of highresolution display tube,the optical signal is transformed into the electric signal by using the CCDphotoelectric sensor,the electric signal is then processed through the microcomputer. resolution ofCRT is detected automatically.This set gives a high measuring accuracy and speed and provides anadvanced test tool for studing and producing high resolution CRT and deflecting yoke.
