Active camouflage technology, both visual and otherwise, is a commonly used plot device in science fiction stories. The Star Trek franchise incorporated the concept ("cloaking device"), and Star Trek: Voyager depicts humans using "bio-dampeners" to infiltrate a Borg Cube without the antagonists realizing they are there.

Multi-spectral camouflage can be applied to individuals, to vehicles, and to buildings. It can take the form of specialised paints or camouflage nets that provide conventional camouflage, reduce the amount of heat given off by an object, and alter the shape and size of its radar signature.
An operational, non-fictional cloaking device might be an extension of the basic technologies used by stealth aircraft, such as radar-absorbing dark paint, optical camouflage, cooling the outer surface to minimize electromagnetic emissions (usually infrared), or other techniques to minimize other EM emissions, and to minimize particle emissions from the object.
And like all other examples of camouflage, aircraft patterns vary widely between countries, aircraft, historical period, and the location that the aircraft was being deployed to.
For example, countershading is very common among land animals, but not for military camouflage. The dominant camouflage methods on land are countershading and disruptive coloration, supported by less frequent usage of many other methods. [4] The dominant camouflage methods in the open ocean are transparency, [5] reflection, and ...
SAP materials, according to the researchers, show great potential to be used in “camouflage systems, smart coatings, display devices”, and even “anticounterfeiting technology”.
Other well-studied examples include the cookiecutter shark (Isistius brasiliensis), the marine hatchetfish, and the Hawaiian bobtail squid. [6] More than 10% of shark species may be bioluminescent, though some such as lantern sharks may use the light for signalling as well as for camouflage. [15]
Camouflage is the use of any combination of materials, coloration, or illumination for concealment, either by making animals or objects hard to see, or by disguising them as something else. Examples include the leopard's spotted coat, the battledress of a modern soldier, and the leaf-mimic katydid's wings. A third approach, motion dazzle ...
