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 still in the development stage, this camera can capture images through clothing made of specific synthetic fibers. By increasing the irradiation level, it is possible to take X-ray-like photos even of underwear such as panties. When we actually used this camera to film junior high school girls and college girls on their way home from school, it clearly captured the realistic shape of their bras, the lines of their panties, and even their exposed pale lower bodies. The vivid scene unfolds before our eyes, captivating the viewer.
