Abstract

Using the real-time holographic interferometry, we have studied the way of variation of thermal expansion coefficient as a function of temperature. For this purpose we have used a particular set-up appropriate to in-situs developing process. In the reconstruction step, the observer will see-through the hologram ,a virtual image which is coincident with the wave diffracted by the object itself, and an interference pattern will appear. If then the temperature of the object is increased, this will cause the movement of fringe. Hype number of displaced fringes give measure to evaluatethe coefficient of the thermal expansion of the object. The corresponding curves is depicted.
