Abstract

A new method recovers phase difference of interfering wavefronts from a pattern of interference fringes, avoiding discontinuity problem. The continuous phase is a solution of the first order differential equation of the interferogram function computed from the fringe intensity profile selected along the pathway over the interferogram.
