本文首先介绍静电聚焦摄象管计算的通用程序;然后介绍物点的选取、电子分布函数、均方根半径,着重介绍调制传递函数MTF的程序编制。我们根据I.P.Csorba提出的象管静电电子透镜调制传递函数计算方法,考虑摄象管的特点而首次编制成功的。在此基础上介绍两种常见典型结构——等直径与不等直径三圆筒系统的计算结果。最后用有关数据论述了计算的可靠性。
In this paper, we first introduce the general procedure of electrostatic focusing camera tube calculation. Then, we introduce the selection of object points, electron distribution function and root mean square radius. The emphasis is put on the programming of MTF. According to I.P.Csorba proposed tube electrostatic electron lens modulation transfer function calculation method, taking into account the characteristics of the imaging tube for the first time successfully compiled. On this basis, two common typical structures are introduced - the calculation results of three cylinder systems of equal diameter and unequal diameter. Finally, the relevant data is used to discuss the reliability of the calculation.
