Paper Abstract

This study aims at estimating a moving heat source with a 3D inverse model and a high spatial resolution. In order to cope with the large amount of computations required in the 3D case, a linear unsteady inverse model based on the principle of superposition has been made. Two concepts are used to reduce the computational time: the first one is linked to ht diffusion time of the eta and the second one is linked to the redundancy of the information. Firstly, numerical test are presented. The, a laboratory experimentation consisted in the estimation of the flux of a moving laser beam is described.
