''[[Active camouflage]]'' (or ''adaptive camouflage'') is a group of [[camouflage]] technologies which would allow an object (usually military in nature) to blend into its surroundings by use of panels or coatings capable of changing color or luminosity. Active camouflage can be seen as having the potential to become the perfection of the art of camouflaging things from visual detection.

''Optical camouflage'' is a kind of active camouflage in which one wears a fabric which has an image of the scene directly behind the wearer projected onto it, so that the wearer appears invisible. The drawback to this system is that, when the cloaked wearer moves, a visible distortion is often generated as the 'fabric' catches up with the object's motion.  The concept exists for now only in theory and in proof-of-concept prototypes, although many experts consider it technically feasible.

It has been reported that the [[British Army]] has tested an invisible tank.<ref>Clark, Josh.
