Paper Abstract

A virtual fringe analysis method can be applied to determine displacement vectors from speckle photographs. A diminishing of the visibility shifts dark and bright fringes from minima and maxima of the cosine. Then not only the bright fringes but the dark ones do give erroneous results. The analysing goemetry can increase a reduction of the visibility. This paper deals the fringe visibility of virtual fringes and its effect to the fringe shifts.
