Abstract

A method of measurement of thermal stress of thin films using real-time holographic interferometry is described, with particular emphasis on specularly reflecting thin films. A few thin film-substrate systems have been used for the measurements. For the copper film on brass substrate and silver on glass theoretical and experimental results are found to agree reasonably well at different temperatures. For the cases of aluminium film and magnesium fluoride film on glass there is a wide discrepancy. However it is pointed out that experimental values are closer to reality.
