介绍高分辨率显示管屏空间特性分析系统。该系统采用ＣＣＤ作为光电转换器，借助于一个结构简单、制作方便、所需驱动率极小（小于０．６Ｗ）的四维移动与定位机构，并利用ＰＣ机进行自动控制和数据处理，光学系统实现自动聚焦，对被测管任意位置上的屏空间特性进行测量。本系统可测量线宽、线间距、调制深度、调制传递函数、空间谐波、光点的亮度分布、光栅畸变等参量。测量误差小于±５％ Introduce the high resolution display tube screen space characteristic analysis system. The system uses CCD as photoelectric converter, with a simple structure, easy to manufacture, the required minimum drive rate (less than 0.6W) of the four-dimensional movement and positioning mechanism, and the use of PC for automatic control and data processing, optical system Achieve auto-focus, measuring the spatial characteristics of the screen at any position on the tube under test. The system can measure parameters such as line width, line spacing, modulation depth, modulation transfer function, space harmonics, brightness distribution of light spots and grating distortion. Measurement error is less than ± 5%
