尽管对于显示管的分辨能力早已有原则的定义:“在图象上分辨出最小细节的能力”,但是具体的表示方式和测量方法又有很多种.所有这些已经引起了很多混乱.本文试图通过回顾和分析提出一种较为合理的方式来表示和测量分辨能力,并因此着重介绍了用脉冲行法测量线宽的具体方法、并对这种方法进行了分析. Although the principle of definition of the display tube has long been defined by the principle of “the ability to discern the smallest details in the image,” there are many other ways of specifying and measuring methods, all of which have caused much confusion.This paper attempts to pass The paper reviews and analyzes a reasonable way to represent and measure resolution. The method of measuring the line width by pulse method is emphatically introduced, and the method is analyzed.
