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 HandbookSpectroscopy: Mastering the Techniques: Spectrochemical analysis employing optical spectroscopic methods is used to monitor the water we drink, the food we eat, the status of human health and the quality of the environment. Such methods are also crucial to the development of safe and valuable industrial processes.The scope of optical spectroscopic instrumentation is indeed very broad. Many analytical methods rely on the interaction of radiation with matter and are often described in the context of quantum and...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.
