When Were Camcorders Invented

November 14th, 2010




Did someone really invent x-ray glasses?

I have trouble believing that this is possible. I found this link on some web page ( http://www.xolllab.com/ ) they claim to have invented x-ray glasses. I honestly don’t know anything about the technology that would be required for something like this. I do know that with some camcorders it is possible to see through things when the camera is in night vision mode. So are the glasses real or not? What do you think?

That’s a hoax.

First, to get x-ray imaging, you need a good x-ray source, which in current technology is given by accelerating electrons in a high potential and them stopping them in a metal plate. The electrons give a characteristic radiation called “brehmstralung” and is in the x-ray region of the electromagnetic sprectrum (you can see this piece of equipment next time you go see your dentist). These glasses do not even have an x-ray source in them.

Second, the x-ray “before” and “after” pictures shown are completely unrealistic. You might be able to see the flesh outline of a person with low-energy x-rays and perhaps some other features, but you will mostly see bright bones and outlines of general features of dense materials (such as that bomb you might be hiding in your bag at the airport).

The way x-ray imaging works is because x-rays are high-energy photons (light) that only stop in dense materials, and the amount of “stopping” depends on the density of the material. You emit x-rays on one side of an object, collect them on the *opposite* side, and generate an image (usually with film) that tells you how much x-rays you got in different places. That’s how you generate images. Thus, clothing items and flesh are very weak to stop x-rays, and do so in small amounts. You cannot use x-rays to only “filter” out the clothing part.

Shenanigans.
