what is optical comuflage?

Question

the science of being invisible

Answer 1

Active camouflage or adaptive camouflage, is a group of camouflage technologies which allow an object to blend into its surroundings by use of panels or coatings capable of altering their appearance, color, luminance and reflective properties. Active camouflage has the potential to achieve perfect concealment from visual detection.

Answer 2

What I know of the concept involves applying just the right amount of artificial lighting with just the right pattern and luminosity to an object that allows it to match the pattern and luminosity of the object's background. Take an army tank sitting on a sand dune, for example. If you would, for instance, put some lighting on the tank that matched the luminosity, color, and pattern of the dune it was sitting on, it would become relatively invisible to watching eyes. In theory, computerized optics could scan the dune and send computer signals to the lighting system on the tank which would then adjust itself to the optical qualities of the dune thus making the tank automatically invisible to human eyes. As the tank moved across the dunes and from lighter areas to darker areas, the computerized optics would continually change the lighting to compensate.

Answer 3

One version is the Dazzle stuff from WWII where ships are painted with bold diagonal patterns that make it difficult to determine the exact shape and speed of the ship.
Most camoflage, manmade or natural, works the same way: if a person is covered with black, green and brown blobs, one color blends into the background, but the shape of the other two is so unlike a man that detecting the shape of a man is more difficult.
