heal.abstract	In this paper the problem of determining a screen in an isotropic and homogeneous thermoelastic medium at low frequencies is considered. We formulate the direct problem for the planar screen in the thermoelastic medium and present an equivalent model for the problem under consideration at low-frequencies based on an non - homogeneous formulation via appropriate Dirac measures. We prove that the corresponding inverse problem of reconstructing the planar screen for two important cases: the thermal stress dislocation and the thermal displacement dislocation from boundary measurements has a unique solution. Finally, we present a reconstruction method for the above cases based on a proper use of certain vector test functions and the application of the two-sided Laplace transform.	en
