Abstract

A well-founded and computationally fast method is presented for filtering and interpolating noisy and
discontinuous wrapped phase fields that preserves both the 2π discontinuities that come from the wrapping
effect and the true discontinuities that may be present. It also permits the incorporation of an associated
quality map, if it is available, in a natural way. Examples of its application to the computation of the isoclinic
phase from photoelastic data and to the recovery of discontinuous phase fields from speckle interferometry are
presented.
