Abstract: The invention relates to a method of sampling and displaying information comprising scanning a beam over the sample in a series of N overlapping sub-frames, each comprising Mn scan positions, thereby irradiating the sample at N×Mn scan positions, which form the field of view; detecting a signal, sampled for each scan position, emanating from the sample; and displaying the sub-frames having at least N×Mn pixels in such a way, that after the series of N scans each of the pixels displays information derived from the signal from one or more scan positions; in which after the scan of the first sub-frame each of the pixels displays information derived from the scan positions of the first sub-frame; and after the scan of the second sub-frame each of the pixels displays information derived during the scanning of the first, the second, or both sub-frames.
