摘要

本文研究了实现图像有任意设定像转角的电磁聚焦成像理论，进一步发展了作者先前的电磁聚焦成像理论，导出了在设定图像转角下轴上电场和磁场应满足的条件，按照本理论不仅可获得直立式，而且可获得任意设定图像转角（或者倒像式）的电磁聚焦成像系统。作为例子，给出了一种解析的轴上电场和磁场分布，可实现设定图像转角且放大率Ｍ＝１或者Ｍ≠１的电磁聚焦成像。

Abstract

A theory of electrostatic and magnetic imaging with any specified image rotation has been studied

and it develops our previous theory of electrostatic and magnetic imaging. The conditions of the axial electric potential and magnetic induction for realizing electrostatic and magnetic imaging with any required image rotation have been given

and the results show that the given theory can realize not only an erect positive image but also a specified rotated image（or an inverted image）. As an example

an analytical distribution of axial electric potential and magnetic induction has been given for obtaining the electrostatic and magnetic imaging with any specified image rotated angle and magnification M=1 or M≠1.
