Paper Abstract

We describe a technique for uniquely recovering the optical path imbalance within an interferometer interferometrically by means of a sinusoidal modulation of the source frequency. The technique is demonstrated in systems configured to measure displacement, intermodal dispersion in a highly birefringent fibre and the refractive index of a number of liquids.
