CIE (L*a*b*) uniform color space. Spectral discomfort glare sensitivity was determined using ten young observers, requesting the observers to select medium glare settings of monochromatic radiations based on the de Boer glare rating scale, both at near‐foveal and 10° extra‐foveal directions of the 2° diameter glare source. The haze can be reduced by shading the lens with a lens hood, which minimizes the glare. Why Do “Left” And “Right” Mean Liberal And Conservative? Spatial–Spectral Evidence of Glare Influence on Hyperspectral Acquisitions. A lower test result means a lens that will allow more light to pass through it. Here, brightness is usually understood what is more precisely called radiance, i.e., we actually have a spectral radiance.

CIE 1988 2° modified spectral luminous efficiency function for photopic vision. Spectral lines are produced by transitions of electrons within atoms or ions. • "Dictionary" definition: A harsh uncomfortably bright light ; especially: painfully bright sunlight • Glare occurs in two ways: – Too much light – Luminance range is too large • Effects of glare: – Photobiological damage: not considered here His brother Niles, also a psychiatrist, is, for a time, married to Maris, a spectral caricature who’s never seen on the show. Color Rendition (of objects): Effect of an illuminant on the color appearance of objects by conscious or subconscious comparison with their color appearance under a reference illuminant. spectral luminous efficiency. 4 Investigation of this concept continued through the 1950s, with the number of bands, their dividing wavelengths, and their relative weighting investigated by numerous researchers. spectral definition: 1. coming from or seeming to be the spirit of a dead person: 2. of the set of colours into which a…. The data acquired from global radiation and direct radiation, together with specific spectral data help to determine the amount of gasses and aerosol particles in the air and also provide information on the photo-chemical formation of secondary impurities. Look it up now! Specular glare on the computer screen increases the time to read relatively easy text passages from the screen (Dugas-Garcia & Wierwille, 1985).

The ultimate high definition vision of everything in sight. of or relating to a specter; ghostly; phantom. The Dictionary.com Word Of The Year For 2020 Is …. Glare, also referred to as flare, is often defined as a Human Visual System (HSV) condition which causes a reduced capability to see details, due to an unsuitable distribution of luminance in the scene [1,2].Unfortunately, the term “glare” is used to refer both to the cause and to the effect of this phenomenon, as in the definition above which is a description of the effects, not of the cause.

The glare is the result of the specular reflection of the beam of light from an oncoming car. distribution temperature of a light source. Use sunglasses to lessen glare. Noun: 1. spectre - a ghostly appearing figure; "we were unprepared for the apparition that confronted us" CIE 1988 2° modified spectral luminous efficiency function for photopic vision. Disabling glare, by definition, can result in reduced visual performance. A type of spectroscopy that measures power spectral density of surface morphology by exploiting the tendency of light to disperse into a range of directions as a result of physical interaction. The atlas is divided into pages for each spectral type, with each page containing a short description of the stellar type, characteristic spectral features, and a brief physical explantaion. Filters can also be attached to reduce lens flare when shooting outside in bright conditions. This spectral atlas contains a sample of the standard spectral type stars, peculiar stars, variable stars, and some special stars. What Does Amen Mean At The End Of A Prayer? The following definitions are from IDA/IES MLO-2011.

Note: UWLR also meets the LEED version 4 definition of percent uplight. glare arising from specularly reflected light. distal stimulus. When something is spectral, it has a ghostlike quality; it seems to vanish or disappear. This is at least the most common definition, leading to units of W/(sr cm 2 Hz). Copyright © 2002, 2001, 1995 by Houghton Mifflin Company. You may recognize the spect part of the adjective spectral from words like "spectacle," "spectrum," and "spectacular." Filters can also be attached to reduce lens flare when shooting outside in bright conditions.
