Researchers at the University of Arizona have advanced 3D-sensing technology. Navigating a chaotic city ...

Imagine navigating a city street during rush hour—cars and bikes zipping by, pedestrians hustling down a crowded sidewalk, ...

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 ...

We attribute the depleted region in the electron beam to strong deflection of the beam electrons by net positive charges in the central region and an expanding cloud of hot electrons. Within the cloud ...

A new method significantly advances 3D imaging of reflective surfaces. The approach integrates techniques known from high-precision optical 3D metrology and computer vision, and could benefit ...

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 ...

Laboratory experiment demonstrating the proof of principle of the new technology. A mixed reflectance scene is scanned with a laser scanner (left). After computational separation of matte and specular ...

Eye tracking plays a critical role in the latest virtual and augmented reality headsets and is an important technology in the entertainment industry, scientific research, medical and behavioral ...
