Abstract
Digital processing improves quality of electron microscope images. The data matrix which describes the image is obtained from the video signal of the STEM- unit of an EM 301.
A digital version of an analog processing method called “defocus masking” may be appropriate for microprocessor implementation. It is compared with other methods of design of two-dimensional filters for electron microscopy.
