Inspection of micromask patterns occurs by both moving an inspecting laser beam relative to a micromask and varying the intensity of said beam in the same manner that occurs during pattern generation. The pattern modulates the inspecting laser beam by one of reflecting or transmitting a modulated laser beam therefrom. The modulated beam then is sensed and used to produce a modulation signal. The m...
