Abstract

Mapping of temperature of a premixed hydrogen-oxygen flame by moire deflectometry is demonstrated.The technique is based on deflection mapping of rays from a collimated light beam due to gradients of the refractive index across the flame. For an axially symmetric flame the radial distribution of the refractive index was derived by Abel transformation. The temperature profile of the flame was calculated for a known gas composition assuming ideal gas behavior.
