The methods of holographic interferometric measurement and reconstruction in 3 dimension temperature field are investigated. The projection data of 3 dimension temperature field is obtained by real time holographic interferometric experiment. In the reconstruction of temperature field, its smoothness is applied. The smooth local base function is used in the temperature field and compared with other ones. It is proved through the numerical analysis and the experiment that the method of local base function is better than the other methods.
