Choosing the best CCD for a given application, however, requires knowing how basic chip parameters affect performance.Since their invention in the late 1960s, charge-coupled devices, also called CCDs, have found widespread use in imaging applications. Electronic cameras based on CCD technology are used in...Photonics HandbookNanopositioning: A Step Ahead: It is almost a cliché among students of creativity that innovation occurs at the intersection of fields. Since nanopositioning is a discipline that has enabled swiftly evolving application arenas as diverse as materials science, genomics, photonics, defense, biophysics and semiconductors, it’s unsurprising that its pace of innovation is nothing short of blistering in recent years.By its original definition, a nanopositioning device is a mechanism capable of repeatedly delivering motion in increments as small as one nanometer. Lately demands from industry and research have...Photonics HandbookNano-Optics Technology: Optical Alchemy: Transforming ordinary materials into extraordinary optics holds the key to progress.Optics today needs alchemy, and the forces that motivate microchip technology are a key reason why.

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 HandbookPHOTONICS BUYERS' GUIDE CATEGORIESAstronomical OpticsAstronomical TelescopesAn astronomical telescope is an instrument used to observe celestial bodies.
