Digital interferometry for measuring of the resin composite thickness variation during blue light polymerization
Digital interferometry device is described for measuring the thickness variations of the resin composite samples during blue light polymerization. The proposed device enables two types of quantitative measurements providing data for: (i) the thickness variations of samples continuously during cure and (ii) the total linear shrinkage of samples. The effects of the initial thermal expansion and the later shrinkage can be clearly resolved for different materials, curing lights, and illumination modes. Simple experimental device is introduced through the results obtained for commercial dental materials.
