The paper presents an experimental application of a method leading to the  identication of the elastic and damping material properties of isotropic  vibrating plates. The theory assumes that the searched parameters can be  extracted from curvature and deection elds measured on the whole surface of  the plate at two particular instants of the vibrating motion. The experimental  application consists in an original excitation xture, a particular adaptation  of an optical full-eld measurement technique, a data preprocessing giving the  curvature and deection elds and nally in the identication process using the  Virtual Fields Method (VFM). The principle of the deectometry technique used  for the measurements is presented. First results of identication on an acrylic  plate are presented and compared to reference values. Details about a new  experimental arrangement, currently in progress, is presented. It uses a high  speed digital camera to over sample the full-eld measurements
