Abstract: The use of wavelength-shifting interferometry with a He-Ne laser source is presented The approach is based on the thermal expansion of the laser cavity during the warm-up time in conjunction with an unequal path interferometric configuration The optics principles are reviewed and a demonstrative measurement is presented The technique extends the capability of phase-shift acquisition and processing to cases where conventional methods with piezoelectric transducers cannot be used and particularly to external measurement cavities of large diameter Published by Elsevier B V
