In the backs of old comics they used to sell amazing devices, the X-Ray Specs were one of them. The magic glasses supposedly let you "See the bones in your hand, see through clothes!"
Not really an X-ray system these were a diffraction grating that blurred the outline of the viewed object (the transparent flesh) and created a darker inner region (the bones)
In the real world similar, but much bulkier and much more expensive systems include:
- Thermal imaging goggles working with infra red light or heat
- Real X-ray systems which require an xray source behinf the object
- Terahertz (or T wave) systems as installed at airports
