Many physical properties of materials are dependent on temperature, therefore the measurement of temperature  distribution is very important. For this, various optical techniques are used widely nowadays in the field of heat and mass transfer measurement. These methods are non-destructive. In a group of optical methods which are called index of refraction methods, the temperature distribution is obtained by measuring the phase differences of light rays caused by variations in refractive index. The phase of the optical wave is affected by the refractive index and therefore measurement of the phase of an optical wave gives useful information about the behavior of the testing sample.
The aim of this thesis is to develop the temperature measurement method by using a single shot off-axis digital holography. For this purpose, we describe a method of the numerical reconstruction of the complete wavefront properties from a single shot off-axis digital hologram: the amplitude, the phase, and the polarization state.
