Digital Holographic Speckle Pattern Interferometry in Structural Diagnostics of Paintings: Toward Displacement-Based Heritage Metrology
A central challenge in the structural diagnostics of paintings is the accurate, repeatable, non-invasive, and ideally non-contact documentation of subsurface defects such as detachments, cracks, and interlayer decohesion, which often precede visible surface deterioration. Beyond the visual detection of damage, preventi...
