In this paper, we present a method of quantitatively measuring in real-time the dynamic temperature field change and visualization volumetric fields generated by 2D axial-symmetric heated fluid from pulsatile jet water tank through off-axis digital holographic interferometry. A Mach-Zehnder interferometer on portable platform was built for experimental investigation. The submerged fed with higher temperature. Tomographic approach used to reconstruct Abel Transform filtered back-projection. Averaged results, tomographic view, standard deviation errors are presented. presented results reveal interferometry as powerful technique visualize flowing liquids gases.
