RIVERSIDE, Calif., June, 18, 2009 – Microscopic polymer beads that change color instantly and reversibly when external magnetic fields acting upon the microspheres change orientation, have been discovered by a research team at the University of California, Riverside. The beads or "magnetochromatic microspheres" have excellent...Read full articleRelated content from Photonics MediaARTICLESLightning Awards 'Luminate' RochesterLuminate — the world’s largest optics, photonics and imaging (OPI) accelerator focused on advancing next-generation OPI-enabled companies — announced at their Luminate Lightning...Photonics Spectra January 2018 IssueFor Ultrafast Photonics, New Applications EmergeUltrafast lasers can do a lot, including create a room-temperature superconductor.

The layer of gases that we breathe also distorts the images formed by telescopes. This means that conventional telescopes of more than a few centimeters in diameter cannot reach the resolution limit set by their optics.To Isaac Newton the problem was clear, and in 1704 he realized the effects of atmospheric turbulence on image formation. Just as heat waves shimmering above a hot patch of ground can distort our...Photonics HandbookSWIR Imaging: An Industrial Processing Tool: Short-wave infrared (SWIR) imaging with InGaAs-based cameras is well suited to nondestructive identification of materials, their composition, coatings and other characteristics.Imaging has long been used in industrial processes to measure, monitor, control or otherwise manage the production of goods.
