Actual See-through Devices
- Thermal imaging goggles are used by various military and police organizations. 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.
- Devices currently in development for airport security are able to see through clothing quite well. These are true X-ray devices, using backscatter X-rays. The devices are not portable and use a typical X-ray display screen, not goggles.
- 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, and Gamma-ray radiography.
- Terahertz imaging uses electromagnetic radiation in the terahertz or far infrared range to see through objects in a similar manner to X-rays. It is currently a very expensive new technology, and is being tested for use in customs inspection, firefighting, search and rescue and medical imaging.
- Some video cameras have a night mode that gives an IR image under the right conditions. Digital cameras can also be used.

Famous quotes containing the words actual and/or devices:
“The true thrift is always to spend on the higher plane; to invest and invest, with keener avarice, that he may spend in spiritual creation, and not in augmenting animal existence. Nor is the man enriched, in repeating the old experiments of animal sensation; nor unless through new powers and ascending pleasures he knows himself by the actual experience of higher good to be already on the way to the highest.”
—Ralph Waldo Emerson (1803–1882)
“Soon silence will have passed into legend. Man has turned his back on silence. Day after day he invents machines and devices that increase noise and distract humanity from the essence of life, contemplation, meditation.... Tooting, howling, screeching, booming, crashing, whistling, grinding, and trilling bolster his ego. His anxiety subsides. His inhuman void spreads monstrously like a gray vegetation.”
—Jean Arp (1887–1948)
