Abstract: A measuring technique with two wavelength laser holographic interferometry is studied. The basic measurement principle with two wavelength laser holographic interferometric technique, the evaluation of the holographic interferograms , the optical arrangement of measurement, the experimental procedure are discussed. A new measurement means is provided for investigating the coupled heat and mass transfer of liquid fuel evaporation existing in rockets, gas engines, diesel engines, boilers and other power machinery.
