Time reversal (TR) method uses backward wave propagation for refocusing and reconstruction of the original source. Aim of this work is an analysis of influence of temperature change on the quality of reconstruction of the original loading pulse. This study clarifies how sensitive the TR method is to slight change of elastic parameters. The temperature change is modelled simply by changing the Young’s modulus of the material.
