As we know from comparing instant capture digital sensors to scanning camera backs, scanners usually have much higher resolution. 3D scanners have higher effective resolution yet because they can supersample each pixel. We now have a confirmation that the scanners used by TSA have high enough resolution for a Penthouse centerfold spread and are being used for similar purposes.
This message came in the email a couple of day ago:
Yesterday my 5'2" 140# 38 DD-fiancee had to go through the pervoscan to go to the gate to pick up her daughter. She was stopped and questioned about the T shaped object in her abdomen; the scan was so detailed it showed her IUD
-not to mention her unmentionables!
Each part of the "T" of the intrauterine contraceptive device is 3mm thick. In other words, the scanners used by TSA are detailed enough to detect a 1/8" object inside a passengers' genitals -- at which point TSA agents question them about the details of their privates! Seems to me that this is far beyond the most depressing predictions by Orwell or Kafka.
If you have technical details of the scanners used by the TSA, I would like to see it to confirm my guesses as to their capabilities. In the absence of such information, we can make certain assumptions about the potential for misuse. We do know that TSA is lying to us by claiming that their equipment shows little detail and only of the skin surface.
