高分辨电子显微象波函数复原的MIMAP方法

The Multiple Input Maximum A-Posteriori Wave Function Restoration Method in High-Resolution Electron Microscopy

本文讨论了波函数复原的MIMAP(multiple input maximum a-posteriori)方法,指出了E.J.Kirkland给出的MIMAP条件所存在的问题,并导出了修正的MIMAP条件。本文还给出了几个波函数复原的计算实例。

Investigating the basic theory of the MIMAP(multiple input maximum a-posteriori)wave function restoration method in high-resolution electron microscopy, we have noted that the MIMAP criterion first proposed by Kirkland (Ultramicroscopy, 15(1984)151)appears objec-tionable. A modified MIMAP Criterion. which is more conformed to Physical reality of the prob-lem, is introduced. The test calculations of the wave function restoration have been perlormed for the multi-slice method simulated defocus series of MgO [110].
