摘要

本文从当代天文光电成像探测器的发展现状与实际需要出发，着重探讨寻求允许输入像面不是平面、放大倍率不等于１的永磁聚焦磁场系统的设计途径，用约束变尺度法来设计在电磁聚焦成像系统中实现给定的不均匀磁场分布的实际永磁环磁路系统。

Abstract

From the practical requirements of new astronomical photoelectronic imaging detectors

much attention has been paid to the design of new permanent magnet focusing field systems

in which curved input-image and demagnification are allowable.The constrained inverse design of the focusing magnetic field in electrostatic and magnetic imaging systems applying new permanent magnet materials is discussed and investigated using the constrained optimization CVM （Constrained Variable Metric） method.
