This article intends to provide an explanation and serve as a...Photonics HandbookIntegrating Spheres: Collecting and Uniformly Distributing Light: The integrating sphere is a simple, yet often misunderstood, device for measuring optical radiation.An integrating sphere’s function is to spatially integrate radiant flux (light). However, before one can optimize a sphere design for a particular application, it is important to understand how...Photonics HandbookRadiometry: A Simplified Description of Light Measurement: Radiometry involves measuring and predicting levels of optical radiation. This article removes some of the confusion surrounding this often complex technology.Radiometry involves several activities. The two most common are the description and measurement of optical radiation, and, starting with the knowledge of some aspects of optical radiation at one...Photonics HandbookAdaptive Optics: Taming Atmospheric Turbulence: For more than three centuries, the Earth’s atmosphere has frustrated astronomers. 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...WHITEPAPERSPhotonics.com 1/14/2021Methods for Measuring Display Defects and Mura as Correlated to Human Visual PerceptionHuman vision and perception are the ultimate determinants of display quality, however human judgment is variable, making it difficult to define and apply quantitatively in research or production...Photonics.com 1/14/2021Fractional Pixel Method for Improved Pixel-Level Measurement and Correction (Demura) of High-Resolution DisplaysAs display resolutions increase, imaging systems are challenged to continue to provide accurate pixel-level measurements while applying increasingly limited relative imaging resolution during...Photonics.com 2/28/2022Optical DomesThe optical dome consists of two parallel optical surfaces (convex and concave).
