Spray combustion modeling requires reliable experimental data on the energetic budget of evaporating and combusting droplets in their gaseous environment. The droplet temperature is a key point in these investigations. The tow colors laser-induced fluorescence has been demonstrated as space averaged droplet temperature measurement technique. In this paper, the possibility to extend this technique in order to obtain the temperature distribution within the droplet is presented. It may provide valuable information about the heat diffusion in the liquid droplet, during the heating phase. The technique is tested on a combusting monodisperse droplet stream, with 200 μm droplet diameter.
