In fantasy, invisibility is often invoked and dismissed at will by a person, with a magic spell or potion, or a cloak, ring or other object.
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.
Invisibility perception depends on several optical and visual factors. [1] For example, invisibility depends on the eyes of the observer and/or the instruments used. Thus an object can be classified as "invisible" to a person, animal, instrument, etc. In research on sensorial perception it has been shown that invisibility is perceived in cycles ...

Work on achieving similar results with visible light is in progress. [ 13 ] [ 14 ] Other types of invisibility cloak are also possible, including ones that cloak events rather than objects. However, cloaking a human-sized object at visible wavelengths appears to have low probability. [ 15 ]
