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 MediaARTICLESPhotonic Crystals Show Fast Response Speeds for Next-Gen DisplaysA technique to restructure liquid crystals could lead to the development of fast-responding liquid crystals suitable for next-generation displays and advanced photonic applications such as mirrorless...Photonics.com 11/11/2019Pure Graphene Generates Photocurrent Over Great DistancesAn international research team has discovered a new mechanism for ultra-efficient charge and energy flow in pristine graphene.

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 HandbookInfrared System Design: Understanding the Process: While equations and data pertaining to infrared system design abound,1 comparatively little has been written about the process.2 This article attempts to fill that void.Infrared system design is not, like some circuit design, a synthetic process.

Rather, we guess a...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.
