ABSTRACT
A method is reported, which allows us to measure the dynamics of the surface thermoelastic deformations. We have obtained the time evolution of amplitudes of surface deformations induced by absorption of a laser beam in Plexiglas samples of different geometry. A qualitative discussion of the obtained results is made.

    The thermal phenomena appear at the level of the film within the primary sealing interstitium. An important temperature gradient is performed in the stator and in the rotor, which produces thermoelastic deformations. These deformations are of the order of film width and affect essentially the...
