摘要
将多重网格法用于静电像管电子光学场分布计算,采用改进的约束变尺度法进行静电聚焦像管的优化设计,较大地提高了电场分布的计算精度和像管设计效率,减少了计算时间和设计周期。研究的加权最小二乘法构造优化计算的多目标函数,普遍适用于调焦、定焦、变倍、选通和校畸变等各种类型静电像管的设计与计算。
The paper describes a constrained variable metric method (CVMM) for the optimization design of image tubes with electrostatic focusing, and a multigrid method (MGM) for the computation of the electrostatic field in designing image tubes, thus to improve the efficiency of field computation, and reduce the time of computation. The functions of least-square-fit form with weight factors for the optimization computation can be generally applied in the design of the diodes and triodes of focusing, zooming, gating and distortion-correcting tubes.
