"Invisible Sunburn" --- How US Intel can TAG/follow a suspect without being on the ground.

The US has technology that can give a person a sunburn, using laser energy.

The surface of the target's skin (or a painted surface, like a vehicle) will radiate energy. The frequency of the laser involved can be modulated, so that the "color" of the sunburn isn't in the visible spectrum. and the wavelength of light the "sun-burn" reflects/radiates will be at a specific frequency. So this means that the person doesn't have a visible sunburn (even though they feel the effects, i.e, hot, tender dry skin, fever, etc); but when viewed in the UV spectrum, they "glow" at a largely coherent frequency, complementary to the frequency they were lased with.

So if, say, prisoners were all lasered with a specific frequency, then US Intel can afterward. use spy satellites to scan crowds or even whole countries for bodies that are giving off that signature---US can see it from space.

So US could "follow them" on camera with a spy satellite, and watch where they go and who they talk too. Maybe even hope they all go to make contact with their supreme cult-leader, showing US where said cult-leader is.

This tech became operational in the Obama era. It could have been used to track down a leader of a terrorist organization, by tagging his known minions and then "following them from space" until they went to the leader's liar where he was receiving dialysis and watching videotapes.

It could have been used again to track down a different terrorist leader, knowing that that tagged escapees would run to his hideout, showing us where he is.

It could have been used to "burn" a car's paint job, the one used by his chauffeur, and then followed for days. But then when it was only used as a decoy for where the cult-leader really was, US would know it because nobody with a "prisoner's sunburn" was having contact with the sunburnt car.

All speculation, of course.

Interesting concept. I could see being "tagged" with a specific radio-isotope being more plausible than this, when it comes to detection, but then, a good scrubbing shower would probably clean it off.

I don't know how either would be detected from any significant distance (maybe it could be - I mean that literally, I just don't know the physics of either radio-isotope or laser "burn" signature detection.)

Could be very cool, useful, and/or scary, depending on whether you're the good guys or bad guys, depending on who is in power.

That hardly scratches the surface of our military capabilities in this respect.

Especially from drones or space.

It's expensive and a pain in the ass to accomplish so tech like this isn't used very often.

We can all thank DARPA for the technology.

And it's all hiding in plain sight. You just have to know where to look.

KEY HOLE / EIS could read a license plate in the mid-high northern latitudes from space. Reading the frequency off of a human's neck/face would be similar.

The resolution wasn't generally that good; that's why software focused on gait to identify individuals (shadows at higher latitudes were long enough to be used to determine gait from 12 miles overhead).

NGEO is supposed to have a lot better resolution. But it won't matter if cheaper/older scopes are used, since it is a unique [I]frequency that confirms it's the same individual. one pixel of 371.6 nm is enough to confirm it is the same human tagged while in detention in some 'rendition' facility in the sandbox that used that specific wavelength.

If the skin is burned, no matter what,it will show red.

Depends on the spectrum that hit it. beta particle radiation will cause "radiation sickness" that shares many of the symptoms of sunburn, but without necessarily having a reddened appearance.

If human hairless skin is exposed to certain light wavelengths, it will be altered and reflect a different spectrum of UV bands than skin that has not been exposed to this treatment. The effects are not always a visible reddening of the skin.
