It is unfortunate to some and a blessing to others, that the technology that could see through skin would now be used to see skin, right through your swimsuit.
Xray glasses on the back of magazines may not be so far from a reality these days as we see sites like XrayHunter.com form showcasing tons of girls Xrayed while enjoying themselves on public beaches.
Excerpt from the site:
What you see here is a new form of “infrared photography” using the “near infrared” light spectrum. You may have heard about this controversial new technology on the news lately! View the ABC news clip here.
All camcorders are made to view and record normal light. (white light). This is between 400 and 750 nanometers. Many common camcorders are equipped with nightvision or nightshot modes and are capable of viewing light higher than 750 nanometers. This is the “near infrared” light spectrum referred to on this chart below:
Waves in this spectrum are not visible to the naked eye but they are visible to the CCD chip in your camcorder. These “near infrared” light waves are the waves that are penetrating the material and reflecting an image of the body surface. The camcorder can pick up all these waves and records them. In order capture the x-ray effect you must block out the visible light waves or they will overtake your image drowning out the infrared image.
Normally the nightshot or nightvision mode was to be used only at night when there is very very little white light or (visible light) as we know it. However there are no girls out on the beach at night so we had to trick the camera into thinking it was night. We do this by screwing a filter on the lens that only lets the “near infrared light” (750 nanometers or more) into the camera. All the visible light waves are blocked out (750 and below). If you were to hold this filter up to the sun you will not be able to see thru it. It is totally black! But when you screw it on the camcorder and look in the viewfinder you can see a perfect black and white image. This is the x-ray vision technology that you see in use here.
In a bid to prevent people taking sneak see-though snapshots of female athletes using infrared photography, a sports equipment manufacturer here has developed underwear that blocks out infrared rays.
The underwear was produced by Cramer Japan. The company’s president, Takashi Hokazono, said he hoped it would help athletes feel more at ease.
“It will probably release them from the fear of not knowing when or by whom they will next be photographed, and allow them to concentrate on their events, leading to better results,” he said.
Infrared rays can pass through many materials, and when taking photographs with special equipment that blocks out visible light, there are cases in which the skin underneath people’s clothing can be captured on film.
In recent years, there has been an increase in the number of people using infrared light to take sneak see-through photographs of female athletes and children at school sports events. Sporting groups and school officials have raised concerns about such photography.
Some swimsuit manufacturers have already released products that block out infrared rays, but there have also been calls for the introduction of protective clothing for other sports. Cramer Japan introduced its products after being approached by the Inter-University Athletic Union of Japan over the problem. It spent two years developing the clothing with textile manufacturer Toyobo, and Toyoshima, a wholesaler and trader of fabrics.
The first item in the line of Cramer Japan’s “Shot Guard” products is a pair of underpants. By blocking out infrared rays with underwear, athletes can wear their uniforms and school sports gear on top without worrying about being secretly filmed.
The company plans to keep improving the material and is set to introduce new products such as breast pads.
“By introducing conditions that make photography more difficult, the number of malicious photographers will decrease, and we hope that our products will be of some help in eliminating such photography altogether,” Hokazono said.
The underwear retails for 2,000 yen apiece.
