Isochromatic fringe multiplication by a factor of up to 17 is demonstrated for slices from three-dimensional frozen-stress models. With this method, sensitivity is increased by an order of magnitude, the taking of data is quick and easy and the interpretation of data is less subject to errors than compensation techniques.
