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 the...
Briefs: Sensors/Data Acquisition
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 may...
Briefs: Test & Measurement
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...
Briefs: Semiconductors & ICs
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. Devices...
INSIDER: Materials
Intentionally “squashing”colloidal quantum dots during chemical synthesis creates dots capable of stable, “blink-free” light emission that is fully comparable with...

The Create the Future Design Contest, launched in 2002 by the publishers of Tech Briefs magazine, helps stimulate and reward engineering innovation. The annual event has attracted...
Briefs: Medical
Researchers at Rensselaer Poytechnic Institute (RPI) have developed a new approach to optical imaging that makes it possible to quickly and economically monitor multiple molecular interactions in a...
Briefs: Photonics/Optics
Researchers have, for the first time, integrated two technologies widely used in applications such as optical communications, bio-imaging, and Light Detection and Ranging (LIDAR) systems. In the...
Briefs: Electronics & Computers
A team of researchers at the New York University Tandon School of Engineering and NYU Center for Neural Science has solved a longstanding puzzle of how to build ultra-sensitive, ultra-small, electrochemical...
Briefs: Photonics/Optics
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...
Briefs: Imaging
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 reconstruct...
Articles: Communications
Since their development in the 1950s, optical fibers have been used for power transmission, communication, imaging, and sensing. They are often used in situations where other sensing techniques...
Briefs: Transportation
An optical setup developed by researchers at Sandia's Combustion Research Facility and the Technical University of Denmark can now quantify the formation of soot — particulate matter consisting...
Briefs: Photonics/Optics
Inspired by the human eye, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed an adaptive metalens that is essentially a flat,...
Briefs: Electronics & Computers
Light is the most energy-efficient way to move information; however, light shows one big limitation: it is difficult to store. Data centers, for example, rely primarily on magnetic hard drives in...

Ultrasensitive Chip-Based Sensors
An optical whispering gallery mode resonator was developed that can spin light around the circumference of a tiny sphere millions of times, creating an ultrasensitive, microchip-based sensor for multiple applications.
Briefs: Electronics & Computers
Existing optics mounts sandwich the optic axially between two metal components, which can lead to optical surface damage and misalignment when exposed to fluctuating temperatures. Thermal-compensating optics...
Briefs: Test & Measurement
Pointing precision is a critical element of instrumentation for optical communications and ranging in space, affecting laser design, link power budgets, and SWaP. While star trackers possess pointing...
Briefs: Manufacturing & Prototyping
Numerous devices in everyday life use computerized cameras to identify objects — think of automated teller machines that can “read” handwritten dollar amounts when...
Briefs: Materials
Liquid droplets are used in many applications, from printing ink on paper to creating microcapsules for drug delivery. Inkjet printing is the most common technique used to...
