Active camouflage is used in several groups of animals including cephalopod molluscs,[2] fish,[3] and reptiles. Animals achieve active camouflage both by color change and (among marine animals such as squid) by counter-illumination, with the use of bioluminescence. It uses about 1000 hexagonal panels to cover the sides of a tank. Deus Ex: Human Revolution,[24] and the Crysis series,[25] players can obtain and use cloaking devices. 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. The main objective of military camouflage is to deceive the enemy as to the presence, position and intentions of military formations. [7][4] Cephalopod active camouflage has stimulated military research in the United States. There is still active debate on how to best "categorize" camouflage.

Animals achieve active camouflage both by color change and (among marine animals) by counterillumination. The panels are rapidly heated and cooled to match either the temperature of the vehicle's surroundings, or one of the objects in the thermal cloaking system's "library" such as a truck, car or large rock. 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. By emitting a small, measured amount of blue light, the aircraft's average brightness better matches that of the sky, and the aircraft is able to fly closer to its target before being detected.

Active camouflage or adaptive camouflage is camouflage that adapts, often rapidly, to the surroundings of an object such as an animal or military vehicle. Generally the tactics involve hindering or preventing detection or recognition. The retroreflectors in the cloth reflect the image back towards the glass plate which being only weakly reflecting allows most of the retroreflected light to pass through to be seen by the viewer. The panels are rapidly heated and cooled to match either the temperature of the vehicle's surroundings, or one of the objects in the thermal cloaking system's "library" such as a truck, car or large rock.

Illustrating the concept, i.e. [10], Active camouflage provides concealment by making an object not merely generally similar to its surroundings, but effectively invisible with "illusory transparency" through accurate mimicry, and by changing the appearance of the object as changes occur in its background. [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. [1] In practice, it is the application of colour and materials to battledress and military equipment to conceal them from visual observation. Some species of cephalopod, such as the eye-flash squid and the firefly squid, produce light in photophores on their undersides to match the background. 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.
