Cargo scanning includes the use of X-ray radiography, dual-energy X-ray radiography, backscatter X-ray radiography, muon radiography, muon tomography, neutron activation systems, or gamma-ray radiography.
#XRAY VISION GLASSES PORTABLE#
The devices are not portable and use a typical X-ray display screen, not goggles. Some of these are true X-ray devices, using backscatter X-rays. Devices for airport security are able to see through clothing quite well.Some video cameras have a night mode that gives an IR image under the right conditions. They are intended for night use, but the longer wavelength of infrared light allows the user to see images through some materials that are impervious to visible light. Thermal imaging goggles are used by various military and police organizations.Their name was used as the inspiration for the UK punk band X-Ray Spex. Instead of glasses, the device was in the form of a small telescope. Ī previous product called the Wonder Tube worked similarly. Patent 3,592,533) by Harold von Braunhut, also the inventor of Amazing Sea-Monkeys. A tubular configuration employing the same principle as well as the use of a feather for the diffraction grating was first patented in 1909 by Fred J. The principle behind the illusion, as well as its use in a pair of "spectacles", was first patented (in the United States) in 1906 by George W.
#XRAY VISION GLASSES HOW TO#
Indeed, instructions with the packaging explain how to provoke such reactions, to "CONVINCE the gals that your X-Ray Spex are for real!" These subjects may believe that the device does allow the wearer to compromise their modesty, so are liable to respond with a variety of amusing reactions. Part of the novelty value lies in provoking the object of the wearer's attentions. In smaller print below the X-ray claims, advertisements and packaging state that X-Ray Specs operate by "illusion". X-Ray Specs were long advertised with the slogan "See the bones in your hand, see through clothes!" Some versions of the advertisement featured an illustration of a young man using the X-Ray Specs to examine the bones in his hand while a voluptuous woman stood in the background, as though awaiting her turn to be "X-rayed". Newer versions utilize manufactured diffraction lenses instead of feathers. Where the images overlap, a darker image is obtained, giving the illusion that one is seeing the graphite embedded within the body of the pencil. For instance, if viewing a pencil, one would see two offset images of the pencil. The vanes of the feathers are so close together that light is diffracted, causing the user to receive two slightly offset images.
In the original version, a feather is embedded between the layers of each lens. The user views objects through the holes. The "lenses" consist of two layers of thin cardboard with a small hole about a quarter-inch (6 millimeters) in diameter punched through both layers.
X-Ray Specs consist of an over-sized pair of spectacles with plastic or cardboard frames and white cardboard "lenses" printed with concentric red circles, and emblazoned with the legend "X-RAY VISION". Viewing the "bones" of a hand through X-Ray Specs
