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 ...

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 ...

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 ...

Accurate and robust 3D imaging of specular, or mirror-like, surfaces is crucial in fields such as industrial inspection, medical imaging, virtual reality, and cultural heritage preservation. Yet ...

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 ...

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 ...
