摘要
提出了一种研究采用图案偏转轭的高分辨率摄像管的新方法。与现有的方法相比,该方法具有速度快、精度高和适用性广的特点。文中给出了该方法的数学模型和程序框图,并利用该方法的计算结果,分析了该种摄像管的电子光学特性和影响各电子光学特性参量的主要因素。
A new method of studying high resolution camera tubes with pattern yokeis presented.Having the advantages of rapidity and accuracy,the method is superior toall other existing methodes used to solve the same problem,and it may be applied to avariety of structures.The mathematical model and the program sketch are given The elec-tron optical properties of the camera tube and the primary factor influencing them arestudied according to the results computed by the presented method.
