Paper Abstract

For measuring displacement fields by means of holographic interferometry interferograms are analyzed with the skeleton method. To get information about phase distribution after constructing the skelton of the fringe pattern by computer-aided digital image processing an interpolation between skeleton lines is necessary. For evaluating phase values on a regular grid three interpolation methods are described and discussed in this paper.
