Abstract

In this paper we present the potentialities of the conoscopic holography sensors for surface analysis of archeological artifacts with a micrometric resolution. The modularity and the portability of the developed setup allow to work in situ with a multiscale and multi-material approach. Moreover, we developed our own tools for creating a mesh from the 2D-arrays of distances collected with the consequent possibility of printing a replica of the artwork using 3D printing technologies. We test the microprofilometer on two case studies: a fragment of an archeological amphora, presenting also the workflow to obtain the 3D printed object, and an Etruscan bronze mirror, analyzing the surface.
