Abstract
Coherent holographic metrology provides the non-contact potential to retrieve directly from surface measurements of the spatial displacement information originating from the bulk of complex objects suffering inherent faults or physical deterioration. These damage factors endanger the structural integrity and lessen the life span of works of art, inevitably reaching the fragile and precious surface. Interferometry techniques via interference fringes offer NDT for surface authentication and impact analysis and overall quality control in order to provide a signature of precious surface responses or exempt faulted products from the production line. In this paper the 2D interferometry information is instead implemented as a NDT to prevent artworks from physical deterioration. It is proposed a structural diagnosis method via 2D spatial data derived from interference intensity profiles. Thus the paper introduces the concept to diagnose the structural condition via direct contactless interference examination of artwork surface with the prospect of timeless documentation in art conservation field.
