Photorefractive crystals (PRCs) are very promising recording materials for holographic interferometry, with which real time testing can be realized since they dont need developing and fixing. The application of holographic interferometry using PRCs as real time recording and reconstruction materials to optical testing has been investigated and the method for the distribution of the temperature field of an alcohol flame has been put forward. The principles, the derivation of the parameters and conditions for experiments, the experimental procedure in detail and final results are presented.
