Paper Abstract

The use of sandwich hologram interferometry makes it possible to investigate objects of interest to an engineer that was not possible to investigate before. The paper presents some different applications of the technique. An application is a study of an object one meter in length, where the object was removed from the holographic setup between exposures and holes were drilled in one wall of the object. The deformation around the drilled holes could be studied, after a second recording of the object repositioned in the holographic setup was performed. Other applications of holographic non-destructive testing are shown where the fringe manipulation possibility is important.
