Interferometric method is used to measure small changes in size of optical materials. Error introduced with optical phase shifts occurring with time is overcome by using parts of Fabry-Perot resonators with unequal lengths. Both stability of optical phase shifts upon reflection from multilayer stacks and dimensional stability of optical contacts is measured.
