Optical Techniques for Relief Study of Mona Lisa’s Wooden Support
We present in this paper an original application of the use of optical methods for the study of the famous painting: Mona Lisa. Several laboratories  have participated to the study of this painting to evaluate the degradation risk, especially in relation with the existing crack and to optimise the conservation conditions, regarding both the humidity regulation and the design of the frame. Mona Lisa is painting on a poplar support, so the aim of our study, is to obtain a whole field 3D profile of the panel on front and back face of Mona Lisa . Furthermore, these values allow us to understand the mechanical impact by the frame in which the panel is maintained attached and are used to describe the hygromechanical behaviour of the wooden painting by many measurements realized during several hours. These experimental data have been used to realize a numerical model of the panel, and also to validate the numerical simulations of the mechanical behavior of the panel [1,3].
