Abstract
For one and a half decade, software for interferometric fringe evaluation has been developed and used at Technical University Graz. Within the framework of an awarded grant to one of the authors, the Austrian Government funded activities on optical metrology in mechanical engineering. In this grant these software packages on interferometric fringe evaluation had been subsumed under Windows95/98/NT and the Unix/X-Window-System. This software is made accessible via internet to the public domain (http://optics.tu-graz.ac.at). Its main features are phase- stepping, Fourier domain evaluation and unwrapping techniques as well as algorithms for Abel-inversion and tomographical reconstruction. Additionally, we implemented a bunch of tools for data manipulation, e.g. multiple file handling, filtering, and flexible visualization of data. Some of these features with examples from a multidirectional holographic measurement on a plasma discharge and from speckle interferometry are presented.
