Claim:
1. A method of accumulating an image of a specimen using a scanning-type microscope, comprising the following steps: providing a beam of radiation that is directed from a source through an illuminator so as to irradiate the specimen; providing a detector for detecting a flux of radiation emanating from the specimen in response to said irradiation; causing said beam to undergo scanning motion relative to a surface of the specimen, and recording an output of the detector as a function of scan position, in a first sampling session S repeating this the procedure of gathering detector data from subsequent collections of sampling points so as to accumulate a set {P assembling an image of the specimen by using the set {P wherein, as part of said assembly process, a mathematical registration correction is made to compensate for drift mismatches between different members of the set {P
