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 HandbookDetectors: CCDs for Life-Science Applications: The CCD camera is becoming the imaging method of choice in biological laboratories for its resolution, versatility and ease of use. 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 HandbookDetectors: The Charge Injection Alternative: Charge-injection device (CID) technology provides a means to convert optical signals from 185 nm to 1100 nm to electronic charges that can be read out as a video signal or processed via computer. The CID imagers also are capable of directly (or indirectly) converting particle photons including electrons, ions, x-rays and other forms of ionizing radiation to measurable levels of electronic charge.Charged-injection device imagers are metal-oxide semiconductor (MOS) detectors that can be fabricated using PMOS, NMOS and CMOS integrated circuit technology, and may be configured as a...Photonics HandbookCommon Infrared Optical Materials and Coatings: A Guide to Properties, Performance and Applications: The purpose of this guide is to identify the most common infrared-transmitting materials, pointing out key properties and their typical manufacturing and optical coating options.
