Abstract

A possibility of restoration of live fringe-pattern phase by means of estimation of separate sections of interferogram is considered. It is possible if the phase is a monotonous function in any section of interferogram. Doing so, on-line interferogram demodulation is realized and, besides, the fringe-pattern vibration effect is reduced.
