roughness measures with Hirox microscope

Abstract
Surfaces of materials from cultural heritage are exceptionally varied as patina, varnish, wear or scratches are added intentionally or with time to the base material, whether it is wood, marble, stucco, or brass. Measuring their texture provides a lot of information to curators but it constitutes a challenging task for the engineer. The present study focuses on the question of texture acquisition by means of two optical micro-topographic instruments. As those
instruments deeply differ in their working principle, it is necessary to check if results are comparable in terms of roughness. Moreover, in order to define the space of materials they are able to record, the study highlighted how the global appearance of an object interferes
with the measurement of its surface relief, because of the design of the utilized instruments.
