Sequential method for thermal diffusivity discrimination by infrared thermography: application to the use of an uncooled plane-array camera

Abstract. A one-dimensional transient flash method based on an infrared thermography device permits retrieval of the thermal diffusivity map. However, each pixel of the temperature image presents a very noisy temporal signal. Moreover, in the case of an uncooled focal-plane-array camera, each plane-array detector presents independent calibration coefficients and independent offset levels.
