On the use of an infra-red camera for the measurement of temperature in fires of vegetative fuels

In this work, we propose an original methodology based on infra-red thermography to measure the temperature in the flames and embers of a fire of vegetation. An infra-red camera provides digital levels in output that can be used to retrieve the temperature of the target. The method usually used to obtain this temperature follows a formalism resulting from the law of Planck. Both relationships were compared for static and spreading fires. The proposed approach provides better agreement with experiments than the classical method.
