A mathematical method to process data provided by a flying spot technique is studied here, by considering the temperature response field around a unique spot. The progress of optical control, laser and IR Camera allow to measure 2D temperature fields localised on a small area compared to the whole recorded image. The study is focused on the logarithmic expression of the in-plane temperature field in order to analyse and to measure different parameters such as the in plane thermal diffusivity
