Optical interferometers, such as the Mach-Zehnder interferometer, have often been used to measure the temperature of transparent fluids. In this paper, we utilize a Moire interferometer in which a conventional interferometer is combined with the Moire technique. By applying a fringe scanning technique to this Moire interferometer, a new fringe analytical system is obtained and the fringe analysis is automated with the aid of a personal computer. The temperature field of the air around a vertical heated plate under natural convection is measured and compared with the theoretical solution. The temperature measured using this system is in good agreement with the theoretical one. It is verified that this optical system is applicable for measuring the temperature of transparent fluids.
