It's been over 100 years since the invention of X-rays, and now the development of X-ray cameras has finally been successful. In addition to conventional infrared technology, it has become possible to take pictures using a uniquely developed light nano laser. Although it is still in the development stage, it has already been realized that it is possible to take X-ray photos through certain synthetic fiber clothing. By adjusting the intensity of the irradiation, it is possible to take X-ray photos of underwear such as panties and bras. When this X-ray camera was used to film a college girl while she was shopping, her underwear was clearly visible, something that is normally impossible to see.
