System and method for characterizing a textured surface

摘要

A textured surface characterization system ( 100 ) includes a characterization apparatus ( 110 ) that contacts a textured surface ( 104 ) of an item ( 108 ) in order to characterize that surface. The characterization system includes a fluid delivery system ( 204 ) for flowing a fluid ( 128 ) across the textured surface when the textured surface is in contact with the characterization apparatus. Pressure measurement structures ( 144, 160 ) on the characterization apparatus provide pressure data for the fluid as it flows across the textured surface. This pressure data is used to characterize the textured surface.
