1. An inspection system, comprising: a stage, for supporting an inspected object and for moving the inspected object by a movement that is characterized by speed variations; a signal generator, for generating triggering pulses at a fixed frequency regardless of the speed variations; a stage location generator, for providing location information indicative of a location of the stage at points of time that are determined by the triggering pulses; a strobe illuminator for illuminating areas of the inspected object in response to the triggering pulses; a camera for acquiring images of areas of the inspected object in response to the triggering pulses; and a processor for associating location information to the acquired images.
