Abstract:
Charging areas in electron microscopy are identified by comparing images obtained in different frames. A difference image or one or more optical flow parameters can be used for the comparison. If charging is detected, electron dose is adjusted, typically just in specimen areas associated with charging. Dose is conveniently adjusted by adjusting electron beam dwell time. Upon adjustment, a final image is obtained, with charging effects eliminated or reduced.

Claim (Index 1):
A charged particle beam (CPB) imaging system, comprising:\n a scannable CPB source configured to scan a CPB at a specimen; a detector situated to produce a signal responsive to scanning the CPB on the specimen; and a system controller coupled to the CPB source and the detector so as to produce at least a first specimen image and a second specimen image based on the signals produced by the detector in response to the scanned CPB and compare the first specimen image and the second specimen image, and based on the comparison, select at least one specimen region associated with a CPB scan induced specimen change.
