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 ...

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 ...

Current eye-tracking methods can only capture directional information of the eyeball from a few sparse surface points, about a dozen at most. With our deflectometry-based method, we can use the ...
