The eigenvalues and eigenfunctions of the imaging integral operator of finite domain in the Hilbert space are studied in detail in this paper. The authors focus attention on the case of asy asymmetrical kernels. The perturbation and finite rank methods are used to inverse the operator equations to obtain the eigenvalues and eigenfunctions for the defocusing systems.
