Abstract
We describe a method for using a pulsed ring heat source to measure thickne sses of thin slabs of material. The method relies on the fact that the ampl itude of the peak temperature in the center of the ring is inversely propor tional to material thickness. A single measurement on a slab of known thick ness of the same material suffices to calibrate the technique for use on sl abs of unknown thickness.
