Researchers have developed a metasurface attachment that can turn just about any camera or imaging system, even off-the-shelf systems, into polarization cameras. The attachment uses a metasurface of ...

Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS Independent manipulations of various properties of EM waves are crucially required in a wide range of ...

Since the concepts of digital coding metasurface and programmable metasurface were put forward in 2014, the physical world of electromagnetics has been closely connected to the digital world of ...

Think of all the information we get based on how an object interacts with wavelengths of light—aka color. Color can tell us if food is safe to eat or if a piece of metal is hot. Color is an important ...

Professor Koray Aydin developed a metasurface spatial filter to improve image processing used in augmented and virtual reality systems, autonomous vehicles, and biometric identification systems. Along ...

A project at Pennsylvania State University (Penn State) has developed a metasurface intended to extract polarimetric imaging data more rapidly and cost effectively than current methods. Described in ...

A new single-layer chiral metasurface detects circularly polarized light efficiently, offering a compact, high-performance alternative to bulky optical systems. (Nanowerk News) Detecting circularly ...

Polarization of light can reveal otherwise invisible information about natural materials and the condition of man-made structures, but the cameras used to detect it are often bulky, expensive, and ...

Researchers have designed a metasurface that can be continuously tuned from linear to elliptical birefringence, opening up the entire space of polarization control with just one device. This single ...

(Nanowerk News) Metasurface technology is an advanced optical technology that is thinner, lighter, and capable of precisely controlling light through nanometer-sized artificial structures compared to ...
