![]() ![]() 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". ![]() It is also excellent for penetrating smoke and other aerosols.Viewing the "bones" of a hand through X-Ray Specs Nevertheless many food colorings eg cola drinks, soy sauce etc are transparent to IR as are many plastic coloring agents. Despite all the rumors only a certain range of synthetic fabrics are completely transparent to IR. This is an excellent area to experiment in with a converted digital camera. ![]() is referring too is using infra red or near infra red. I believe he deliberately wore it as a clue for the joke. (4) The image is obviously faked, the bones are in the wrong places, the ring on the finger would appear black in an X-ray. In fact X-rays are usually made as contact prints to avoid the problems of focus. (3) The lenses of a digital camera cannot focus X-rays. Think about if X-Rays of any strength were coming from the sun it would make any form of photography virtually impossible. ![]() (2) You also need a strong source of X-Rays Solar X-rays aren't enough. Without a special phosphor layer it could not act as a down converter. It is readily available from X-Ray equipment suppliers. (1) Beryllium is used as an X-ray window material as it passes X-rays but not visible light. Some consideration must be given to the fact that this Instructable was released to coincide with April the 1st. (We also wouldn't recommend bringing the stuff with you on your next trip to North Korea.) If you do manage to track down a small piece, here's how to mod your camera and give it superpowers. And though it's technically not illegal, you can't buy the material from any reputable store. This will prevent your digital "film" from being overexposed by too many different wavelengths. The filter converts X rays into visible light by using an optical down conversion process to lower the energy of the photons. PopSci got its sample from NASA during a visit to the Goddard Space Flight Center a few years ago, as it is sometimes used in satellites to block out cosmic X rays that might distort digital communications. Here's the catch: The key is in a hard-to-find X-ray conversion material called a beryllium window. It won't give you Superman vision, but you should be able to see through one or two layers of paper and fabric (again, behave!) in the right light. While we don't support such nefarious uses, you can make your own working X-ray camera, just by modifying a CVS Disposable. You've seen them in the back of magazines-heck, probably Popular Science-all your life: the crazy swirling paper X-ray specs, with the campy '50s pervert looking at the bloomers of a shocked gal. ![]()
