New Algorithm to Improve Optical-Based Hand Gesture Recognition

In the 2002 science fiction blockbuster film Minority Report, Tom Cruise's character John Anderton uses his hands, sheathed in special gloves, to interface with his wall-sized transparent computer screen. The computer recognizes his gestures to enlarge, zoom in, and swipe away.

Holography: Origins, Problems, and Possible Solutions

Most people own at least one hologram, probably without knowing it's a hologram. Those with relatively little optical background, most of the general public, are most likely to encounter real holograms, face to face, in museums, magazines, art galleries, holographic displays, and security devices (such as those on credit cards).

New Filter-Free Imaging Sensors Could Improve Low-Light, Fast Imaging

Newly developed pixel-scale metasurface lenses—flat surfaces that modify light using nanostructures—have been demonstrated to help create imaging sensors that are about three times more sensitive than those now in use. The new sensor architecture may allow digital cameras to image faster or in low-light circumstances.

Color-Sorting Metalenses Boost Imaging Sensitivity

Researchers have shown that newly designed pixel-scale metasurface lenses — flat surfaces that use nanostructures to manipulate light — can be used to make imaging sensors that are roughly three times more sensitive than those used today.
