Paper Abstract

A modified Stroke filtering technique is applied to high resolution micrographs of a conventional transmission electron microscope (CTEM). In a coherent optical processor synthetic holograms are used. They are produced by an analog electron-optical device. A micro-processor-controlled electron beam writes the amplitude component on a fluorescent screen. This image is photographed through an alternately shifted grating. The defects of defocus, spherical aberration and axial astigmatism can be reduced.
