Abstract

We present some results of experimental study of modal dispersion measurement using a simple technique for determination of time-delay of optical beams based on low coherence interferometry in Michelson configuration usually used for chromatic dispersion measurement. The time delay observed at experiments is induced by modal dispersion of modes with small difference of their phase constants. For determination of the character of the modes was used a polarisation measurement.
