Deflectometry is an advanced optical metrology technique designed to evaluate the three-dimensional (3D) shape of specular, mirror-like surfaces. By analysing the deformations in reflected patterns, ...

A pattern of distorted lines is visible as a reflection in this close-up view of a human eye. By observing the deformation of illumination patterns reflected off the eye's surface, researchers in ...

Defects on the metal separator of fuel cells are three-dimensionally measured for real-time inspection during the production process. Fuel cells, integral components ...

An optics lab at the University of Arizona (UA) is using new 3D imaging techniques based on deflectometry to create innovative eye-tracking technology, with apps ranging from entertainment headsets to ...
