Abstract

A holographic method for detecting detached regions between the priming layers and the underlying wood support in panel paintings is described. Experimental results obtained by the application of the method both on laboratory models and on an ancient Italian panel painting are presented. The great advantages that this technique can offer to the conservation and restoration of works of art are emphasized.
