Curious about exactly how the TSA manages to see you naked? Well, the actual technology is pretty high end (and proprietary), but it is possible to come up with something close. The process is quite complicated, and the person who worked out the process hasn’t documented it completely, but you can get the basic idea from the video.
The project uses a hand scanner, as well as multiple feed horns from satellite dishes; one is reversed to transmit, and the others are left as receivers, allowing the radar to see objects at a centimeter level instead of a millimeter level (but it still works). Quite the interesting project really, and it shows how the future of scanning technology may come from the enthusiast sector rather then your typical security sources.
