高分辨率显示管线宽测试仪

介绍用ＣＣＤ传感头探测高分辨率ＣＲＴ和显示屏的新型仪器。它由ＣＣＤ传感头将光信号转换成电信号，由微机进行信号处理，实现自动测量。本方法测试精度高、测量速度快，为研制、生产高分辨率ＣＲＴ和偏转线圈的用户提供了一种先进的测试手段。

Test Instrument of Line Width of High Resolution Display Tube

A new instrument for detecting the high resolqtion CRT and display with CCD sensor is introduced. It transforms the optical signal into the electric signal by using the CCD photoelectric sensor. The electric signal is then processed by the microcomputer.The high resolution CRT is detected automatically and objectivly. This detecting method guarantees a great accuracy and measuring speed and provides an advanced test method for users in studying and producing high resblution CRT and deflecting yoke.
