Abstract

During processing of fringes interferogram, a missing data of the interferogram fringes in area of the aperture edge make difficulties for positioning of the equal-phase lines. It results in mistakes of the phase surface recovering at boundary of the interferogram area. Inaccuracy of building of the equal-phase lines in the marginal area directly connected with the width of the interference fringes. In this paper the method of interference fringe tracing in the marginal interferogram area is proposed, the influence of extrapolation of the equal-phase lines on the accuracy of the phase recovering is investigated, results of closed numerical experiments on the interferogram processing are presented.
