Direct measurements of boundary conditions in application such as descaling or hot rolling in steel industry or in experiments that simulates these processes are impossible. Thus temperature histories are recorded inside the investigated body. The distance of the measurement point from the investigated surface strongly influences the shortest impulse that can be reconstructed by an inverse method. The time delay dependence on distance of the measurement point from the surface is shown in this paper. According to this time delay and quality of the measurement device a minimal number of forward steps are computed for sequential Beck’s inverse algorithm. Based on the number of forward steps the degradations of reconstructed boundary conditions are presented.
