Shaping Light with a Smartlens

High quality camera performance on mobile devices has proven to be one of the features that most end-users aim for. The importance of optical image quality improvement and the trend to have thinner and thinner...

A new imaging method extracts a color image from a single exposure of light scattered through a mostly opaque material.

UCLA engineers have made major improvements on their design of an optical neural network — a device inspired by how the human brain works — that can identify objects or process...

Most of us know optical lenses as curved, transparent pieces of plastic or glass, designed to focus light for microscopes, spectacles, cameras, and more. For the most part, a...

Understanding how cars, planes, bridges, and other structures handle vibrations and dynamic loads can be critical to their design and performance. Researchers have developed a new way to...

Magnetic resonance imaging (MRI) machines are employed to locate cancerous tumors and aid in the development of treatment plans, while nuclear magnetic resonance (NMR) machines are used to...

Antenna Near-Field Probe Station Scanner

Antenna characterization techniques are often expensive and time-consuming. NASA’s Glenn Research Center developed a highly versatile and automated system to perform characterization of single or multiple small circuit antennas, printed on-wafer or on other substrates, by measuring the antenna’s...

A 3D-printed polymer-based foam structure was developed that responds to the force of a shock wave to act as a oneway switch, a long sought-after goal in shock research. The...

Since 1998, almost 2,000 shoebox-sized satellites known as CubeSats have been launched into space. Due to their small frame and the fact that they can be made from off-the-shelf...

A breakthrough imaging technique developed by Cornell researchers shows promise in decontaminating water by yielding surprising and important information about catalyst particles that can't be...

When light gets scattered as it passes through a translucent material, the emerging pattern of “speckle” looks as random as static on a television screen with no signal. But it...

Autonomous vehicles relying on light-based image sensors often struggle to see through blinding conditions such as fog. Sub-terahertz wavelengths, which are between microwave...
