Broad-range holographic contouring of diffuse surfaces by dual-beam illumination: study of two related techniques

摘要

This paper reports on two holographic techniques that 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.
