Briefs: Test & Measurement
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...
Briefs: Nanotechnology
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 of...
Briefs: RF & Microwave Electronics
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: Mechanical & Fluid Systems
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...

Measurement Technique for Continuous-Wave, Modulated, and Pulsed Monochromatic Radiation
In many applications, such as remote sensing of atmospheric trace gases, monochromatic radiation with multiple discrete wavelengths is required. To date, there no instrument or technique that measures the wavelength jitters and fluctuations in real time.

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: Lighting
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
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: Medical
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: Imaging
It's hard to get an X-ray image of low-density material like tissue between bones because X-rays just pass right through like sunlight through a window. Sandia studies myriads of low-density materials, from...
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...
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...

Single-Crystal SiGe/Sapphire Epitaxy
NASA's Langley Research Center has developed a new low-temperature method of SiGe/sapphire growth that produces the same single-crystal films with much less thermal loading effort to the substrate. This eliminates the time-consuming and costly high heating, long thermal soak times, and interfacial Si layer....
Briefs: Photonics/Optics
An innovative optical sensing and tracking system was designed to detect, track, and determine object distance and direction in a wide, full, solid angle (160 × 160°) with an extremely high...

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: Materials
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: Aerospace
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: Materials
Existing nanosensor technologies depend on an external power source (typically a battery) to operate. Chemical and biological sensors based on nanowire or nanotube technologies exhibit...
Briefs: Mechanical & Fluid Systems
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...
