Along with providing users with sights and sounds, some VR systems also deliver tactile sensation to the hands. A new ultrasound-based setup, however, lets users feel the virtual world on and in their ...

Remote ultrasonic arrays made of visible and invisible laser radiation are used to provide ultrasonic images of the interior of solids such a metal parts. Adaptive Laser Induced Phased Arrays are ...

Detecting objects underwater isn’t an easy challenge, especially when things get murky and dark. Radio waves don’t propagate well, so most techniques rely on sound. Sonar is itself farily simple, ...

To establish ultrasonic testing and derived technique capability (phased array and time of flight diffraction) focusing on the nuclear applications to facilitate service to the nuclear industry and ...

A team of researchers at UC Santa Barbara has found a new phenomenon that underpins emerging holographic haptic displays and has the potential to develop more engaging virtual reality experiences. The ...

Field-programmable gate arrays (FPGAs) are a critical component of both digital and hybrid phased array technology. Powering FPGAs for aerospace and defense applications comes with its own set of ...
