Light is widely used for communications, carrying phone conversations and video signals through fiber optic cables around the world in pulses composed of many photons. Single...

Microwave signals are ubiquitous in wireless communications but interact too weakly with photons. A technique was developed to fabricate high-performance optical microstructures using lithium niobate, a material...

Researchers have integrated two technologies widely used in applications such as optical communications, bio-imaging, and Light Detection and Ranging (LiDAR) systems to create a new infrared light-focusing...

Researchers have constructed a “metamirror” device capable of perfectly reflecting sound waves in any direction. The proof-of-principle demonstration is analogous to looking...

Most 3D printers, including light-based techniques, build up 3D objects layer by layer. This leads to a “stair-step” effect along the edges. They also have difficulties creating flexible...

Existing techniques for creating nano-structures are limited in what they can accomplish. Etching patterns onto a surface with light can produce 2D nano-structures but doesn’t work for 3D structures....

New adversarial techniques developed by engineers at Southwest Research Institute can make objects “invisible” to image detection systems that use deep-learning algorithms. These techniques...

A team of bioengineers supported through a Small Business Innovation Research grant from the National Institute of Biomedical Imaging and Bioengineering (NIBIB) has...

One of the frontiers of medical diagnostics is the race for more sensitive blood tests. The ability to detect extremely rare proteins could make a life-saving difference for many...

A Northwestern University research team has developed tiny optical elements from metal nanoparticles and a polymer that one day could replace traditional refractive...

Researchers at the University of Houston have created an inexpensive system that can detect lead in tap water at levels commonly accepted as dangerous, using a lens made with an...

Additive manufacturing, or 3D printing, is a rapidly growing field in which solid objects can be produced layer-by-layer. This...

Anyone who skis, wears glasses, uses a camera, or drives a car is familiar with the problem: Coming into a humid environment from the cold causes eyewear, camera lenses, or windshields to...

Thin, durable heating patches were created using intense pulses of light to fuse tiny silver wires with polyester. Their heating performance is nearly 70 percent higher than similar patches. The inexpensive...

NASA Langley Research Center has developed new methods for fabricating hollow nanoparticles using dendrimer molecules. Dendrimers are used as templates to control the size, stability, and solubility...

Many devices use light to probe the quantum states of atoms in a vapor confined in a small cell. Atoms can be highly sensitive to external conditions, and therefore make superb detectors....

Optical range measurements, already used in manufacturing and other fields, may help overcome practical challenges posed by structural fires, which are too hot to measure with conventional...

Ordinary WiFi can easily detect weapons, bombs, and explosive chemicals in bags at museums, stadiums, theme parks, schools, and other public venues using a low-cost suspicious...

GPS signals do not penetrate very deeply or at all in water, soil, or building walls, and therefore can’t be used by submarines or in underground activities such as surveying mines. GPS also...

Along with intensity and color, polarization is a property of light that can provide useful information for scene analysis; however, the human eye and most cameras cannot detect...

Innovators at NASA’s Glenn Research Center have developed a hybrid telescope antenna system — Teletenna — to deliver high-data-rate communication over great distances. Teletenna has...

Sponsored by the Office of Naval Research's (ONR) TechSolutions program, the Flashing Light to Text Converter (FLTC) features a camera that can be mounted atop a signal...

The diagnosis of diseases based in internal organs often relies on biopsy samples collected from affected regions. But collecting such samples is highly error-prone due to the...

Researchers have developed an imaging technique that uses a tiny, super sharp needle to nudge a single nanoparticle into different orientations and capture 2-D images to help...
