Electrically Tuned Active Metasurface towards Metasurface-Integrated Liquid Crystal on Silicon (meta-LCoS) Devices Active metasurfaces add a new dimension to static metasurfaces by introducing tunability, and this has received enormous attention from industry. Although various mechanisms have been proposed over the past...

From Star Trek ’s Holodeck to Iron Man ’s helmet, science fiction has set the bar high for real-time 3D holographic images. But while we are still pretty far from that, we are getting closer. To appreciate the potential of 3D, think about how we get information about the world around us. The visual is very important: about...

Many fields such as industrial manufacturing require 3D surface profile measurement with nanometre precision. Achieving this precision requires an instrument with incredibly high component accuracy. In this interview, Professor Daping Chu, explained why high precision 3D surface measurement is so difficult, and he described his solution and its advantages, and how it might be commercialized.

CPDS researchers have developed a new augmented reality (AR) head-mounted display (HMD) in collaboration with Huawei European Research Centre, in Munich. The HMD delivers a realistic and comfortable 3D viewing experience, without the commonly associated side effects of nausea or eyestrain. It can deliver high-quality clear...
