German physicist Wilhelm Röntgen is usually credited as the discoverer of X-rays in 1895, because he was the first to systematically study them, though he is not the first to have observed their effects. Roentgen called it “X” to indicate it was an unknown type of radiation. The name stuck, although (over Roentgen’s objections), many of his colleagues suggested calling them Roentgen rays. They are still occasionally referred to as Roentgen rays in German-speaking countries.
The methodology used to create x-ray images is still a matter of confusion to many people. The fact you need an x-ray source and a special x-ray sensor to produce an image makes the fabrication of the infamous “X-Ray Specs” a matter of science fiction. That’s why Chris Baraniuk’s article titled “The Secret History of X-Ray Specs” caught my eyes. The single fact you need to ask the question shines some light on the confusion about the technology. Remember that in the early days some people made money riding the wave of mystery and confusion with “products” like these:
Unfortunately some x-ray companies still rely on these “smoke and mirrors” techniques to sell x-ray machines. That’s why we spend a lot of our time doing the best we can to educate our customers about x-ray inspection. What’s possible, and perhaps more importantly, what’s not possible.
