Abstract

A computer code has been developed to solve numerically the Howie-Basinski equations of electron diffraction theory, and has been applied to simulate diffraction contrast images of small dislocation loops under weak-beam diffraction conditions. In this paper we describe the basis of the code, and apply it to simulate weak-beam images of small loops under a variety of imaging conditions.
