Paper Abstract

This paper reports on two holographic techniques which allow one to obtain the contour maps of arbitrarily shaped objects. The most important feature of these methods is that their sensitivities can be varied continuously and in real-time in a wide range. The intersection planes can be pivoted at will to provide for oblique slicing of the models.
