Micro metal beads generate considerable heat under electromagnetic wave irradiation. In this paper, we measure the temperature gradient of these particles based on interferometry microscopy. Micro metal particles produced by using chemical coating method. For measuring the temperature of these particles under laser irradiation, Mach-Zehnder interferometry microscope have been applied. The phase of the transmitted beam from the particle environment obtained by analyzing interferometry fringes, using Fourier and phase shift fringes analyzing methods. Considering phase distribution and using Abel integral the distribution of refractive index around the particles has been calculated. Finally the temperature gradient determined by using the relation between the refractive index and temperature.
