Abstract:
1. An examining system for imaging an object which is positionable in an object plane, comprising: an illumination device for supplying energy to a delimited field of the object such that charged particles emerge from locations of the delimited field, the delimited field being displaceable in the plane of the object; a first deflector for providing a variable deflection field for guiding charged particles emerging from locations of a selectable region of the object; a position-sensitive detector disposed in a beam path such that the charged particles, after having passed through the first deflector impinge on the position-sensitive detector, wherein particles emerging from different locations of the selectable region of the object are imaged on different locations of the position-sensitive detector which are allocated to the locations of emergence; and a controller for controlling the illumination device to change the displacement of the delimited field and for controlling the first deflector such that the selectable region of the object imaged on the detector is displaced together with the illuminated field in the object plane.
