Sensor Combination Detects People by Smell

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...

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...

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...

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...

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...

Retinal Prosthesis Stimulates Nerve Cells

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...

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...

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...

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...

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...

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...

Cellphones, laptops, tablets, and many other electronics rely on their internal metallic circuits to process information at high speed. Current metal fabrication techniques...

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...

Researchers have developed a method to simultaneously control diverse optical properties of dielectric waveguides by using a two-layer coating, each layer with a...

When hit with light, semiconductors (materials that have an electrical resistance in between that of metals and insulators) generate an electric current....

Piezoelectric Thrust Vector Control for Hall Effect Thruster

The design of the CubeSat required precision pointing of the thrust vector through the spacecraft center of gravity to minimize fuel usage for attitude correction. Because the center of gravity shifts over the course of the mission, a means of adjusting the thrust vector was needed....

Researchers at the UCLA Samueli School of Engineering have demonstrated that deep learning, a powerful form of artificial intelligence, can discern and enhance...

Nano/Micro Mechanical Environmental Test Cell

A device and method have been developed to conduct compression and tensile tests on soft materials such as flocculated sediments, biopolymers, biological materials, and food stuffs. The device...

Microtesting Rig

The measurement of mechanical behavior in very small samples whose dimensions are on the order of microns and below can offer advantages over conventional macroscopic testing in many instances. Motivations for investigating...

Artificial intelligence (AI) has been used to teach wireless devices to sense people's postures and movement, even from the other side of a wall. RF-Pose uses a neural network to analyze...

A next-generation X-ray beamline now operating at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) brings together a unique set of capabilities to measure the...

Optoelectronic engineers in China and Hong Kong have manufactured a special type of liquid crystal display (LCD) that is paper-thin, flexible, light, and tough. With this, a daily...

Autonomous Crop-Counting Robot

Today's crop breeders are trying to boost yields while preparing plants to withstand severe weather and changing climates. To succeed, they must locate the genes for high-yielding, hardy traits in crop...

Hydraulic-Based Spherical Robot

Current spherical robots rely upon rotating mechanical weights inside the sphere to change the center of gravity of the sphere, causing the robot to roll. The use of rotating mechanical weights is not optimal due to the reliance upon moving parts, which can present burdensome maintenance issues. It would be...

Hybrid Optics for Color Imaging

Today's glass-based lenses are bulky and resist miniaturization. To address the problem, two different imaging methods — a type of lens designed for nanoscale interaction with lightwaves, and robust...

Portable Brain Imaging System

Currently, concussion is measured by the symptoms someone experiences, but it is difficult to know what is happening in the brain in any one person. To address this problem, a portable brain imaging system was...

Positional sensors have applications where a very accurate measurement of position is needed over a limited range. One example of such an application is in manipulation of a...
