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 ...

Deflectometry is a 3D imaging technique that allows for the measurement of reflective surfaces with very high accuracy. Common applications of deflectometry include scanning large telescope mirrors or ...

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 ...
