In science fiction stories or superhero comics, X-ray vision is the supernatural ability to see through normally opaque physical objects at the discretion of the holder of this superpower. The most famous possessor of this ability is DC Comics' iconic superhero character, Superman.
Among the best known figures with "x-ray vision" are the fictional Superman, and the protagonist of the 1963 film X . The first person with X-ray vision in a comic book was Olga Mesmer in 1937's Spicy Mysteries. She is often considered to be one of the first superheroes. [1] In myth, Lynceus of the Argonauts possessed a similar ability. [2] [3]
Although called X-ray vision, this power has little to do with the actual effect of X-rays. Instead, it is usually presented as the ability to selectively see through certain objects as though they are invisible or transparent in order to see objects or surfaces beyond or deep inside the affected object or material. Thus, Superman can see through walls to see the criminals beyond, or see through Lois Lane's dress to determine the color of her underwear (in Superman: The Movie , Warner Brothers, 1978). In such cases, the visions seen are generally in full color and in three dimensions. How such an effect might be created via x-rays is unexplained (the x-rays from the viewer's eyes would need to bounce back to their eyes the same way normal light reflects off objects and into the viewer's eyes: x-rays simply pass through an object and continue on their way. X-ray films are made as x-rays pass through an object and then through the x-ray film. The images seen on x-ray film are "shadows" of the objects the x-rays passed through on their way to the film). As depicted, x-ray vision is actually more of a form of the supposed psychic ability of remote viewing.
X-rays have many practical uses for scientific and medical imaging. Security agencies are experimenting with applications of imaging devices which can "see" through clothing (using terahertz waves). Such devices are being deployed in some airports as a way of detecting contraband, such as guns, knives, and any other weapons in particular which may be carried beneath a person's clothing, bag, etc. The devices have created some degree of controversy from personal privacy advocates who worry about screeners being able to see people "naked." There also exist certain night-vision equipped cameras that can be modified to see through clothing at a frequency just below visible light. Such imaging is not true x-ray vision, but rather shows variations in heat radiation rising from the skin beneath the clothing which can provide some detail of the body beneath.
In comic books in the latter half of the 20th century, there often appeared an advertisement for "X-ray specs" which displayed the face of a smiling boy wearing glasses with spirals on the lenses looking at his hand through which he could see the bones.
While X-rays cannot be used in practice to enable seeing objects through walls, researchers have recently shown how everyday wireless signals, such as wi-fi, can be used to achieve x-ray vision. [4] [5] [6] [7] [8] [9] [10] [11]
A superhero or superheroine is a stock character that typically possesses superpowers, abilities beyond those of ordinary people, and fits the role of the hero, typically using their powers to help the world become a better place, or dedicating themselves to protecting the public and fighting crime. Superhero fiction is the genre of fiction that is centered on such characters, especially, since the 1930s, in American comic books, as well as in Japanese media.
Wi-Fi is a family of wireless network protocols based on the IEEE 802.11 family of standards, which are commonly used for local area networking of devices and Internet access, allowing nearby digital devices to exchange data by radio waves. These are the most widely used computer networks in the world, used globally in home and small office networks to link devices together and to a wireless router to connect them to the Internet, and in wireless access points in public places like coffee shops, hotels, libraries, and airports to provide visitors with Internet connectivity for their mobile devices.
Ultra-wideband is a radio technology that can use a very low energy level for short-range, high-bandwidth communications over a large portion of the radio spectrum. UWB has traditional applications in non-cooperative radar imaging. Most recent applications target sensor data collection, precise locating, and tracking. UWB support started to appear in high-end smartphones in 2019.
Bizarro is a supervillain/anti-hero appearing in American comic books published by DC Comics. The character was created by writer Otto Binder and artist George Papp as a "mirror image" of Superman, and first appeared in Superboy #68 (1958). Debuting in the Silver Age of Comic Books, the character has often been portrayed as an antagonist to Superman, though on occasion he also takes on an antihero role.
Terahertz radiation – also known as submillimeter radiation, terahertz waves, tremendously high frequency (THF), T-rays, T-waves, T-light, T-lux or THz – consists of electromagnetic waves within the ITU-designated band of frequencies from 0.3 to 3 terahertz (THz), although the upper boundary is somewhat arbitrary and is considered by some sources as 30 THz. One terahertz is 1012 Hz or 1000 GHz. Wavelengths of radiation in the terahertz band correspondingly range from 1 mm to 0.1 mm = 100 µm. Because terahertz radiation begins at a wavelength of around 1 millimeter and proceeds into shorter wavelengths, it is sometimes known as the submillimeter band, and its radiation as submillimeter waves, especially in astronomy. This band of electromagnetic radiation lies within the transition region between microwave and far infrared, and can be regarded as either.
X: The Man with the X-ray Eyes is a 1963 American science fiction horror film in Pathécolor, produced and directed by Roger Corman, from a script by Ray Russell and Robert Dillon. The film stars Ray Milland as a scientist who develops a method to extend the range of his vision, which results in unexpected complications. Comedian Don Rickles co-stars in one of his few dramatic roles. Diana Van der Vlis and veteran character actor Morris Ankrum also make appearances.
A hotspot is a physical location where people can obtain Internet access, typically using Wi-Fi technology, via a wireless local-area network (WLAN) using a router connected to an Internet service provider.
Gesture recognition is a topic in computer science and language technology with the goal of interpreting human gestures via mathematical algorithms. It is a subdiscipline of computer vision. Gestures can originate from any bodily motion or state, but commonly originate from the face or hand. Focuses in the field include emotion recognition from face and hand gesture recognition since they are all expressions. Users can make simple gestures to control or interact with devices without physically touching them. Many approaches have been made using cameras and computer vision algorithms to interpret sign language, however, the identification and recognition of posture, gait, proxemics, and human behaviors is also the subject of gesture recognition techniques. Gesture recognition can be seen as a way for computers to begin to understand human body language, thus building a better bridge between machines and humans than older text user interfaces or even GUIs, which still limit the majority of input to keyboard and mouse and interact naturally without any mechanical devices.
X-ray specs or X-ray glasses are an American novelty item, purported to allow users to see through or into solid objects. In reality, the spectacles merely create an optical illusion; no X-rays are involved. The current paper version is sold under the name "X-Ray Spex"; a similar product is sold under the name "X-Ray Gogs".
Legion of Super Heroes is an American animated television series produced by Warner Bros. Animation, adapted from the DC Comics series of the same name.

Mobile data offloading is the use of complementary network technologies for delivering data originally targeted for cellular networks. Offloading reduces the amount of data being carried on the cellular bands, freeing bandwidth for other users. It is also used in situations where local cell reception may be poor, allowing the user to connect via wired services with better connectivity.
