摘　　要：本文对有限视场成象积分算子的理论进行讨论,利用在零级本征函数空间展开的方法,得到积分算子本征函数的近似表达式,并借助于实验中测得的脉冲响应(点扩散函数)的数据,算出具有对称性象差的显微物镜的本征值和本征函数,并进行讨论。The theory and approach of the eigenvalue problems of the imaging integral operator of finite domain are discussed in detail. The approximation solution of the imaging integral operator equation is derived by expanding the eigenfunctions in the space of the zeroth-order eigenfunctions. The eigenvalues and eigenfunctions for real microscopic objectives with symmetric aberrations are calculated in terms of the measured LSF data. The experimental system is described and the results are discussed.
