Researchers at the Fralin Biomedical Research Institute at Virginia Tech Carilion School of Medicine (VTCSM) received a $2.4 million National Institutes of Health grant to use optically pumped magnetometry to explore neural activity during face-to-face human interactions. The researchers will optically measure the brain’s magnetic signals in two research volunteers simultaneously as the volunteers interact, capturing the nuances of the brain’s signaling in real time. Brain cells generate electrical currents that emit tiny magnetic fields. Optically pumped magnetometers use...Read full articleRelated content from Photonics MediaARTICLESFraunhofer Tests Lasers for Magnetic Field-Based DiagnosticsResearchers from the Fraunhofer Institute for Applied Solid State Physics (Fraunhofer IAF) demonstrated the principle of laser threshold magnetometry for the first time, they said.

These articles will provide the tools optics designers need to tailor their designs to the appropriate manufacturing process and to optimize the cost of component fabrication.Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot. For example,...Photonics HandbookCamera Resolution: Combining Detector and Optics Performance: Most image-quality discussions center on resolution, which is thought to uniquely determine system performance. Resolution, however, is a more complex concept.Camera resolution depends upon the optical blur diameter and the detector size.
