N2 - A digital method of evaluating interferograms was developed in order to extract the maximum amount of information from interferograms of complex-flow phenomena in shock tubes such as ionizing-gas shock structures and their induced laminar boundary layers as well as real-gas nonstationary oblique-shock-wave diffractions. The method is based on a new approach to the interpretation of interferograms. In this approach the spatial coordinates (x, y) of the various lines of interference (fringes) on the interferogram are put into digital form, thereby readily making computer analysis possible. The new method is not only many times faster but it also removes most of the painstaking drudgery from evaluating interferograms and provides for greater accuracy and insight.
