Geometrical projection identity-based 3D reconstruction for fringe projection profilometry
Optics Letters
|October 15, 2025
Abstract:
This Letter reveals two special geometric points and a geometric projection identity (GPI) within an FPP system, thereby providing new 3D reconstruction equations for four common methods (Ver3, Hor3, OptE3, and HorVer4). We prove that the GPI-based and the traditional reconstruction frameworks are equivalent, but the former enables much faster point cloud computation and effective analysis of precision for metrology.

Fischer Projections
16.2K
Learning to draw Fischer projections of molecules and understanding their relevance plays a crucial role in the visual depiction of organic molecules. A Fischer projection is a two-dimensional projection on a planar surface to simplify the three-dimensional wedge–dash representation of molecules. This is especially helpful in the case of molecules with multiple chiral centers that can be difficult to draw. Here, all the bonds of interest are represented as horizontal or vertical lines. While...

Atomic Force Microscopy
4.4K
Atomic force microscopy (AFM) is a type of scanning probe microscopy that can analyze topographic details of various specimens like ceramics, glass, polymers, and biological samples. AFM offers over 1000 times more resolution than the optical imaging system. Images generated from AFM are three-dimensional surface profiles, offering an advantage over the flat, two-dimensional images from other imaging techniques.
