Popis: Digital interferometry based device for measuring the thickness variations of the resin composite materials during blue light polymerization is described. The proposed device enables two types of quantitative measurements providing data for the total displacement and the dynamic behaviour of displacement. The effect of the thermal expansion as well as polymerization shrinkage can be clearly resolved between different materials, curing lights and modes. The effectivness of our experimental device is illustrated with selected results obtained for a commercial dental material.
