X-ray vision
X-ray Vision
X-ray vision (/ˈeksˌrā ˈviZHən/) is a term often used in popular culture to refer to the ability to see through physical objects, in the manner of X-ray radiography.
Etymology
The term "X-ray vision" is derived from the X-ray, a form of electromagnetic radiation discovered by Wilhelm Conrad Roentgen in 1895. The term "vision" comes from the Latin "visio", meaning "sight".
Concept
In the context of superhuman abilities, X-ray vision is often depicted as the ability to see through solid objects, typically with the exclusion of certain materials depending on the source material. This concept is often used in comic books, science fiction, and fantasy genres.
In reality, X-ray vision as depicted in fiction does not exist. However, technology such as X-ray imaging and Computed Tomography (CT) scans can create images of the inside of solid objects, including the human body.
