Holographic interferogram analysis from a single view.
Quantitative analysis of a holographic interferogram requires either multiple interferograms and hence a great deal of data or strict a priori assumptions. This work presents a class of assumptions that reduces to one the number of views necessary for three-dimensional motion. The method involves relating points on the body via rigid-body theory and calculating deviations from this ideal deformation. It requires knowledge of the expected deformation. An example is given using internally pressurized spherical shells.
