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.
