  • Abstract
    The classical technique of dual wavelength interferometry is used to determine the absolute OPD of very short cavities using a parametric plot of the relative interferometric intensities. A network of eight sensors is demonstrated with phase resolution of 1.5 mrad corresponding to 0.2 nm with an unambiguous range of 114 μm
