Köhler illumination is a method of specimen illumination used for transmitted and reflected light (trans- and epi-illuminated) optical microscopy. Köhler illumination acts to generate an even illumination of the sample and ensures that an image of the illumination source (for example a halogen lamp filament) is not visible in the resulting image.
Global illumination (GI), or indirect illumination, is a group of algorithms used in 3D computer graphics that are meant to add more realistic lighting to 3D scenes. Such algorithms take into account not only the light that comes directly from a light source (direct illumination), but also subsequent cases in which light rays from the same source are reflected by other surfaces in the scene ...
Rainbow. A colorful rainbow and ring-billed gull. A rainbow is an optical phenomenon caused by refraction, internal reflection and dispersion of light in water droplets resulting in a continuous spectrum of light appearing in the sky. [1] The rainbow takes the form of a multicoloured circular arc. [2]

Originally from the Netherlands, the five youngsters joined forces in 2006 and released the A Dozen Dreams EP. After that, a time of intensive touring followed: in the first year they played 70 shows in the Netherlands, England, Wales, Germany, France and Belgium. Destine also shared the stage with bands like New Found Glory and Fall Out Boy.
Freshwater aquarium lighting is commonly provided by screw-in incandescent bulbs, fluorescent tubes and LED lamps. Incandescent lighting is becoming less popular because it uses much more energy and produces more heat than the other lighting types. [1] Compact fluorescent lighting with a compatible screw-in base is frequently used as a direct ...
As Wallace explains, "Savannah as we know it rests on the triumphs of its women — mothers, entrepreneurs, authors, patriots, philanthropists. I created the Savannah Women of Vision investiture to illuminate trailblazers and their transcendent work, keeping their names and deeds not only in our hearts but publicly acclaimed. These are our ...
Synthetic-aperture radar ( SAR) is a form of radar that is used to create two-dimensional images or three-dimensional reconstructions of objects, such as landscapes. [1] SAR uses the motion of the radar antenna over a target region to provide finer spatial resolution than conventional stationary beam-scanning radars.
