Abstract

A Michelson interferometer-based approach was developed to accurately measure the axial shrinkage dynamics and topography of fast curing resin-based composites. The main components of the apparatus consist of a helium–neon laser and a charged coupled device camera with an acquisition rate of 122 frames per second capable of measuring shrinkage rates of up to 19.3μm/s at a spatial resolution of 20.6 μm. The accuracy of the data obtained using this approach was determined by comparison with data obtained using spherical concave mirrors of known focal lengths, and with data collected using a photodiode and stylus-based profilometer.
