本文利用付里叶分析从所要求的光学分辨率导出了对于CRT数据显示的光点尺寸要求。相似的分析方法还可以用来分析荫罩节距对于彩色显示光学性能的影响。关于亮度和对比度之间的关系也进行了讨论。
This paper uses the Fourier analysis to derive the spot size requirements for the CRT data from the required optical resolution. Similar analysis methods can also be used to analyze the effect of shadow mask pitch on the color display optical performance. The relationship between brightness and contrast is also discussed.
