Abstract: The aim of this work is to show how 3D techniques can be used to integrate standard diagnostic ones, adding useful and powerful tools for the restorers. A 3D model allows both to monitor restoration processes and to keep trace of any significant modification of an artwork. We present 3D measurements carried out on different kind of samples: a statue, a painting, a xylography board and two ancient coins. These surveys were carried out by means of a high-resolution laser micro-profilometer developed by the Art Diagnostic Group of the National Institute of Applied Optics. It is composed of a commercial distance meter mounted on a scanning device and allows dense data sampling with high quota resolution and accuracy.
