MULTIPLE-BEAM reflexion fringes, as developed by Tolansky 1, have many advantages over the normal transmission fringes in their application to problems associated with precise measurement, and ...

In particular, it has been demonstrated that properly trained deep neural networks (DNNs) can retrieve phase and unambiguous 3D coordinates of complex objects from only a single fringe pattern ...

An easy-to-replicate project uses Raspberry Pi for accurate interference fringe analysis. I'm starting to think there's a holy trifecta amongst DIY enthusiasts, including 3D printers, SBCs ...
