Abstract

Excimer laser ablation utilized in artwork restoration generates pressure waves that may influence the structural integrity. By means of holographic interferometry a non- destructive highly sensitive mapping for evaluating the structural state is provided. The long-term sequential recording enables comparison between time resolved optical wave fronts scattered from the artwork before and after the selective ablation of material. Thus, comparative structural monitoring of laser-induced photomechanical effects that may result in potential damage of the artwork is accomplished.
