Advanced Imaging for Quantum Materials Research
Modern quantum activity is very broad, encompassing both near-term commercial applications and long-term theoretical challenges. The “first wave” of quantum technology has been defined primarily as the discovery of quantum mechanics and principles of wave-particle duality. The “second wave” is based on the application of fundamental quantum principles such as superposition and entanglement to create highly practical new quantum technology, including exponentially faster computational methods and ultrasecure communications.

Photoluminescence Spectroscopy Optimizes Perovskite Quantum Dots
Perovskite semiconductors have attracted tremendous attention in recent years because of the rapid rise of perovskite solar cell efficiencies — from less than 10% to more than 20% in less than five years — and the potential for the materials to provide low-cost solar power. The properties that make these materials well suited as absorber layers in solar cells also make them excellent emitters of light, and researchers have shifted their attention toward material optimization for optoelectronic applications such as lasers, lighting, and displays. Of particular interest for display applications are perovskite quantum dots (QD), which combine the desirable properties of perovskite semiconductors with the excellent control of the light emission offered through quantum confinement.

Consumer AR/VR Headsets Focus on Nontraditional Optics
The promise of commercial augmented and virtual reality (AR/VR) technologies seems always to be just around the corner. Nearly three decades have passed since the Sega Corporation announced its Sega VR gaming headset, which was one of the first of its kind. But the Japanese company could not produce it in volume for home use.

When One Eye Isn't Enough
AOS Technologies AG
In some applications, one camera is not enough — for example when an issue needs to be observed from different angles, or if there is a need for a color and a NIR camera (near-infrared) recording the same object. The PROMON SCOPE G3 TWIN System is a new tool — perfectly suited for production line optimization and troubleshooting in the field of beverage and food production...

Researchers Use 3D Printer to Print Chalcogenide Glass
Researchers have successfully 3D-printed chalcogenide glass, a material used to make optical components that operate at mid-IR wavelengths. The ability to 3D print this glass could make it possible to manufacture complex glass components and optical fibers for new types of low-cost sensors, telecommunications components, and biomedical devices.

In a new imaging technique developed at Duke University in collaboration with Oak Ridge National Laboratory, short strands of DNA were labeled with fluorescent, temporal “barcodes” for observing biochemical activity at the molecular scale. This time-based approach could improve optical multiplexing of biochemical events. Here is how the technique works: During the interaction between two complementary strands of DNA as they collide in a solution, one DNA strand is attached to

Ed Barnes, of the Virginia Polytechnic Institute and State University (Virginia Tech) Department of Physics, will use a National Science Foundation (NSF) CAREER grant to create mathematical models that will help scientists better understand materials that possess exotic properties. The $494,000, five-year grant will allow Barnes, an assistant professor, to build a new mathematical framework to predict how currents induced by light or magnetic fields will flow in topological materials.

Stabilizing the Line of Sight: LOS Dynamics and Control
Thu, Jun 6, 2019 1:00 PM - 2:00 PM EDT
This webinar, presented by the author of Stabilizing the Line of Sight (Photonics Media Press, 2018), will provide an overview of the issues and topics that must be addressed to successfully implement Line of Sight (LOS) control and stabilization design. Presenter Peter Kennedy will cover LOS pointing, tracking, and stabilization, with a focus on LOS definition, performance, architecture, and basic theory. He will provide a general methodology for LOS stabilization system design and identify critical algorithms for analyzing stabilization techniques. The objective of the webinar is to provide attendees with a firm grounding in LOS stabilization, so that they will be able to address the detailed design tasks required to perform an actual design.
