Engineers at Duke University have developed a way to extract a sequence of images from light scattered through a mostly opaque material — or even off a wall — from one long...
Briefs: Imaging
A new method of X-ray scanning will allow for the visualization of many more biological molecules, providing critical information about what is inside molecules to scientists who...
Briefs: Imaging
Painting of surfaces having numerous facets and/or curved surfaces is a time-consuming process that requires the application of several coats (layers) of paint. Such surfaces are often found on...
Briefs: Aerospace
The ability to fly at supersonic speed without producing unsettling sonic booms would re-open a path to faster commercial aviation. In pursuit of aerodynamics that would...
Briefs: Photonics/Optics
Researchers at Dartmouth have found a way to make back surgery safer, faster, and more cost effective. MRIs and CT scans can help surgeons identify spine problems such as...

A stainless steel alloy — alloy 709 — has potential for elevated-temperature applications such as nuclear reactor structures. It is exceptionally strong and resistant to damage when exposed to high...
Briefs: Medical
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: Imaging
Automated Fiber Placement (AFP) machines can be susceptible to tow-tape defects such as gaps and overlaps. These can reduce strength between 7% and 32%....
Briefs: Nanotechnology
Light of different colors travels at different speeds in different materials and structures. This is why we see white light split into its constituent colors after refracting through a...

Researchers funded by the National Institute of Biomedical Imaging and Bioengineering (NIBIB) have developed a non-invasive imaging technique that accurately detects skin cancer...
Briefs: Sensors/Data Acquisition
For more than 100 years, X-rays have been used in crystallography to determine the structure of molecules. At the heart of the method are the principles of diffraction and superposition, to...
Briefs: Materials
The ability of additive manufacturing to manage small volumes, create complex designs, and fabricate lightweight but strong structures makes it a natural fit for aerospace...

Trained rescue dogs are the best disaster workers — their sensitive noses help them track down people buried by earthquakes or avalanches. But dogs need breaks. A new measuring device is always ready...
Briefs: Imaging
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...
Briefs: Photonics/Optics
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...

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: Medical
Medical image registration is a common technique that involves overlaying two images, such as magnetic resonance imaging (MRI) scans, to compare and analyze anatomical differences in great...

Active Pointing Monitor for a 2-Axis Optical Control System
NASA Goddard Space Flight Center has developed a pointing measurement detection and control system that monitors the real-time optical axis motions (such as tip and tilt) that affect image quality in aerial platforms. To date, there is no known real-time optical image alignment and control...
Briefs: Nanotechnology
Fabricated using inexpensive and widely available organic pigments used in printing inks and cosmetics, an artificial retina was developed that consists of tiny pixels like a digital camera sensor on a...
Briefs: Imaging
Many low-cost sensors (or cameras) may spatially or electronically under-sample an image. Similarly, cameras taking pictures from great distances, such as aerial photos, may not obtain detailed...
Briefs: Photonics/Optics
The underwater environment may appear to the human eye as a dull-blue, featureless space. However, a vast landscape of polarization patterns appear when viewed through a camera that is...
Briefs: Photonics/Optics
Traditional cameras — even those on the thinnest cellphones — cannot be truly flat due to their optics. The lenses require a certain shape and size in order to function. A new camera design...
Briefs: Test & Measurement
An advanced, highly compact thermal camera that traces its heritage to one now flying on NASA's Landsat 8 has been mounted in a corner of NASA's next...
Briefs: Medical
Researchers at the University of Illinois at Urbana-Champaign and Washington University in St. Louis have developed a surgical camera inspired by the eye of the morpho butterfly. The...

MIT researchers have developed novel photography optics that capture images based on the timing of reflecting light inside the optics instead of the traditional approach...
Briefs: Electronics & Computers
Cellphones, laptops, tablets, and many other electronics rely on their internal metallic circuits to process information at high speed. Current metal fabrication techniques tend...
Briefs: Photonics/Optics
MIT researchers have designed an optical filter on a chip that can process optical signals from across an extremely wide spectrum of light at once, something never before...
Briefs: Materials
Researchers have developed a method to simultaneously control diverse optical properties of dielectric waveguides by using a two-layer coating, each layer with a...
