Reflections about holographic and non-holographic acquisition of surface topography [article]

Gerd Häusler, Florian Willomitzer
2021 arXiv   pre-print
We discuss fundamental similarities and differences of holographic surface topography measurement versus non-holographic principles, such as triangulation, classical interferometry, rough surface interferometry  ...  We demonstrate that the question "is holography just interferometry?" has different answers, depending on how we exploit holograms or interferograms for metrology.  ...  Digital holography and quantitative phase contrast imaging using computational shear interferometry.  ...

2005 Journal of Physics, Conference Series  
The main objective of this technical advance is to provide a single optical interferometric framework and methodology to be capable of delivering both nano-scale static and dynamic surface profilometry  ...  In view of this need, a microscopic prototype based on white-light stroboscopic interferometry and the white light vertical scanning principle, was developed to achieve dynamic full-field profilometry  ...  To enhance the scanning efficiency, optical microscopic interferometry, digital holography (DH) and electronic speckle pattern interferometry (ESPI) can all be applied to out-of-plane vibration measurements  ...
