Pulsed laser vaporization (PLV) production of single-wall carbon nanotubes (SWNTs) on traditional Co/Ni catalyst was explored with respect...
Briefs: Sensors/Data Acquisition
Many applications require detection of both very small and very large signals. High-gain detector amplifiers provide low noise, but are easily swamped by large signals. Logarithmic amplifiers provide a wide...
Briefs: Manufacturing & Prototyping
A controllable material was developed that can transform into complex, pre-programmed shapes via light and temperature stimuli, allowing it to morph into a different shape before fully...
Briefs: Imaging
A device that shows the difference between healthy fingers and arthritic fingers has been developed that combines ultrasound and photoacoustics medical imaging techniques. Combining these...
Briefs: Materials
Egyptian blue, derived from calcium copper silicate, was routinely used on ancient depictions of gods and royalty. Previous studies have shown that when Egyptian blue absorbs visible light, it then...
Briefs: Electronics & Computers
3D printing allows for the efficient manufacture of complex geometries. A very promising method is direct laser writing in which a computer-controlled focused laser beam acts as a pen and produces the desired...
Briefs: Mechanical & Fluid Systems
Gyroscopes are devices that help vehicles, drones, and wearable and handheld electronic devices know their orientation in three-dimensional space. Originally, gyroscopes were sets of nested wheels, each spinning on a...

Low-Light Night Vision Imaging and Video Capture
Conventional night vision goggles all use image intensification (I2) tube technology that multiplies ambient, visible, and near-infrared light several thousands of times, allowing a user to see and operate in very-low-light conditions. One shortcoming of I2 tube night vision devices is that they...
Briefs: Transportation
A process has been developed that enables the production of a 2-mm flat camera. The lens is partitioned into 135 tiny facets, similar to the eyes of an insect. The facetVISION camera is suitable...

Optimetric Measurements Over Coherent Free-Space Optical Communication
High-precision ranging (optimetric) instruments are highly desired for both space navigation and communications as well as gravitational-based science missions. Traditionally, these measurements are made with instruments solely dedicated to ranging (i.e. Doppler shift of a...
Briefs: Communications
The first laser based on the wave physics phenomenon called bound states in the continuum (BIC) has been developed. The technology could revolutionize the development of surface lasers,...
Briefs: Materials
The detection and localization of gas releases, such as methane from leaking natural gas pipelines or nitrogen oxides from failing electrical equipment, require high sensitivity to the target gas and insensitivity to...
Briefs: Automotive
It is relatively easy to measure small movements of large objects, but is much more difficult when the moving parts are on the scale of nanometers, or billionths of a meter. The ability to accurately...
Briefs: Test & Measurement
Spectrometers are widely used for applications such as chemical analysis, remote sensing, quality control, environmental monitoring, spaceborne measurements, and optical measurements. Most spectrometers are...
Briefs: Photonics/Optics
NASA Langley Research Center has developed a novel optical grating device that dynamically modulates light and is capable of controlling the spectral properties and propagation of light...
Briefs: Photonics/Optics
Today's photovoltaic power systems are generally comprised of a single photovoltaic module or multiple modules connected by combinations of series and parallel circuits as a photovoltaic array. In...
Briefs: Communications
There are challenges involved when using magnetically responsive materials to achieve the one-way flow of light in a photonic chip, including the ability to place compact magnets on a chip. In...
Briefs: Sensors/Data Acquisition
A blue-light imaging method was developed that can be used to obtain visual data from large test fires where high temperatures could disable or destroy conventional electrical and mechanical sensors. The...
Briefs: Medical
Most naturally occurring materials have a disordered atomic structure that interferes with the propagation of both sound and electromagnetic waves. When the waves come into contact with these...
