Active camouflage Some animals have the ability to change their colors and patterns to help them blend in with their surroundings.

W. Tyler, R. L. Gregory, D. Rogers-Ramachandran, S. Duensing, C. Pillsbury & C. Ramachandran (29 February 1996). In the sea, light comes down from the surface, so when marine animals are seen from below, they appear darker than the background. More recent research has aimed to achieve crypsis by using cameras to sense the visible background, and by controlling panels or coatings that can vary their appearance. An invisibility cloak using active camouflage by Susumu Tachi. Active camouflage is used in several groups of animals, including reptiles on land, and cephalopod molluscs and flatfish in the sea. Active camouflage is used in several groups of animals, including reptiles on land, and cephalopod molluscs and flatfish in the sea. Contents[show] Welcome to the Camouflage wiki. Adaptiv is an active camouflage technology developed by BAE Systems AB to protect military vehicles from detection by far infrared night vision devices, providing infrared stealth. Definition of adaptiv in the Definitions.net dictionary. Military counter-illumination camouflage was first investigated during World War II for marine use. [16], In 2010, the Israeli company Eltics created an early prototype of a system of tiles for infrared camouflage of vehicles. [12] The Yehudi lights project placed low-intensity blue lights on aircraft. The main objective of military camouflage is to deceive the enemy as to the presence, position and intentions of military formations. Change your default dictionary to American English. [15], Phased-array optics (PAO) would implement active camouflage, not by producing a two-dimensional image of background scenery on an object, but by computational holography to produce a three-dimensional hologram of background scenery on an object to be concealed. Communication New! [8], Active camouflage by color change is used by many bottom-living flatfish such as plaice, sole, and flounder that actively copy the patterns and colors of the seafloor below them. If the active camo is active during Campaign, the player is completely invisible to the AI enemies unless they fire their weapon. Some species of cephalopod, such as Abralia veranyi and Watasenia scintillans, produce light in photophores on their undersides to match the background.

[4] There are two mechanisms of active camouflage in animals: Counterillumination camouflage,[2] and color change.

Camouflage is weakened by motion, but active camouflage could still make moving targets more difficult to see. Using visual data from a camera, an object could perhaps be camouflaged well enough to avoid detection by the human eye and optical sensors when stationary. [8] Bioluminescence is common among marine animals, so counterillumination camouflage may be widespread, though light has other functions, including attracting prey and signalling. Artificial systems that replicate functional attributes of the skins of cephalopods could offer capabilities in visual appearance modulation with potential utility in consumer, industrial, and military applications. [11], Military interest in active camouflage has its origins in Second World War studies of counter-illumination. In theory, active camouflage could provide perfect concealment from visual detection. Unlike a two-dimensional image, the holographic image would appear to be the actual scenery behind the object independent of viewer distance or view angle. Using visual data from a camera, an object could perhaps be camouflaged well enough to avoid detection by the human eye and optical sensors when stationary. A video projector projects this image on to the glass plate which is angled so that it acts as a partial mirror reflecting a small portion of the projected light onto the cloth.
