Abstract

In interferometric essays the measured phase merges the topography and index of refraction. Multiple wavelength illumination, variation of the index of refraction of the surrounding medium in containing cambers are common methods to separate those two features of the samples. In this work we present the use of the change of the air pressure on a perfusion camber to decouple the topography and index of refraction. The method is applied to fully characterize a partially stripped optical fibre.
