Abstract
In this paper we apply digital holographic interferometry as a structural diagnosis tool to investigate some surface defects in a XIX century wooden icon. We use a fully digital experimental set-up for real time acquisition and digital optical reconstruction of holographic sequences. The light source is a He-Ne laser, the digital recording component consists of a CCD camera and a spatial light modulator (SLM) works as a digital holographic projector for the optical reconstruction of the interferograms. Both the acquisition set-up and the reconstruction one are functioning simultaneously therefore the changes in the surface structure are visualized in real-time like a digital holographic interferometry “fringe motion picture” with a 20 fps display. Detachment defects of the paint layer are identified using this non-destructive method and the real-time feature has proven to be useful because it gave a very useful dynamicity to the entire investigation process.
