A longstanding partnership between Virginia Polytechnic Institute and State University (Virginia Tech) and Pratt & Whitney has resulted in a new laser-optical technology that aims to revolutionize in-flight thrust measurement.
Given its effectiveness pretreating metal surfaces, industrial laser systems are increasingly being used in manufacturing facilities. The systems can be integrated into automated inline processing lines, or technicians can use mobile handheld units.
The race for very high resolutions places increased demands not only on display manufacturers, but also on the suppliers of light measurement technology.
While the promise of smaller, better, faster, lighter devices enabled by integrated photonics technologies is indeed the ultimate goal for AIM Photonics, the actual path to high-volume manufacturing isn’t necessarily a smooth ride for PIC designers, developers, and engineers.
Rensselaer Polytechnic Institute’s Moussa N’Gom has devised a method to make communications between satellites and the ground more effective — regardless of the weather.
A research team has developed a 3D imaging sensor that has an extremely high angular resolution — it can distinguish points of an object separated by an angular distance, of as little as 0.0018°. The sensor operates on a unique angle-to-color conversion principle.
Engineers have created full-motion video technology that could potentially be used to make cameras that peer through fog, smoke, driving rain, murky water, skin, bone, and other media that reflect scattered light and obscure objects from view.
Researchers have demonstrated an energy-efficient method for transferring larger quantities of data over the fiber-optic cables that connect the nodes. This new technology improves on previous attempts to transmit multiple signals simultaneously over the same fiber-optic cables.
A team of researchers led by electrical engineer Marko Lončar at SEAS has developed a method for building a highly efficient integrated isolator that’s seamlessly incorporated into an optical chip made of lithium niobate.
Researchers have developed a colloidal synthesis method for alkaline earth chalcogenides. This method allows them to control the size of the nanocrystals in the material.
A team at Delft University of Technology has built a new technology on a microchip by combining two Nobel Prize-winning techniques for the first time. This microchip could measure distances in materials at high precision — e.g., underwater or for medical imaging.

Innovators at the NASA Glenn Research Center have developed the PLGRM system, which allows an installed antenna to be characterized in an aircraft hangar. All PLGRM components can be packed onto pallets, shipped, and easily operated.
A wavelength of visible light is about 1,000 times larger than an electron, so the way the two affect each other is limited by that disparity. Now, researchers have come up with a way to...
The effect of displacement currents due to dielectric relaxation of majority carriers in the charge-neutral region of a semiconductor photodiode is discussed. The dielectric relaxation is often...
