Claim 12:
13. An examining device for examining a coating of a probe surface, comprising a processor in communication with a memory, and further comprising:
a providing unit configured for receiving sensing data indicative of a depth of the coating at each of a predetermined subset of probe surface points,
a determining unit configured for determining a depth representation of the coating from the sensing data, wherein the determined depth representation comprises a topographic map of the coating of the probe surface, and
a deriving unit configured for deriving a coating property based on the topographic map, wherein deriving the coating property based on the topographic map comprises:
generating a depth histogram (H) by:
a) counting, for each of a plurality of predetermined depth intervals, a number of the probe surface points in the subset for which the coating depth indicated by the topographic map lies in the respective depth interval, and
b) associating the counting results with the respective depth interval.
