Okay, tin foil hat time.
Maybe they have new machines that can see the print through the paper, and actually scan and store the contents of all these papers in a timely fashion?
- swiley 9y agoThere was an MIT reasearcher a while ago (it may have been posted here) using THz wave radar to do this. I think it's the same band (ish) the body scanners use.
- tjalfi 9y agoWere you thinking of Terahertz time-gated spectral imaging for content extraction through layered structures[0]? [0] https://www.nature.com/articles/ncomms12665 https://www.nature.com/articles/ncomms12665
- wyldfire 9y agoI kinda doubt those body scanners have anything remotely close to the spatial resolution required to find text written on a sheet of paper.
- CyberDildonics 9y agoHe said the same band. That wouldn't have anything to do with spatial resolution.
- wyldfire 9y agoSorry. I inferred that suggesting this meant (in the vein of this "tinfoil hat time" thread) that the body scanners might have the capability to read text from paper.
- coldpie 9y agoThis is only tangential (I don't think the TSA is doing this), but this is similar to a fascinating technique for finding writing on discarded paper used as filler in bindings and such in old books. https://medievalbooks.nl/2015/12/18/x-rays-expose-a-hidden-medieval-library/ https://medievalbooks.nl/2015/12/18/x-rays-expose-a-hidden-m...
