[Ultra-Tech/Fantasy] The One Ring Invisibility vs. TL9 Hyperspectral Goggles?

[LokRobster]

As cross-genre Infinite Worlds craziness continues, our "heroes" have visited Middle Earth again. It's basically a Myth-parallel, it started off close to Classic Tolkien but has veered off - the PCs introduced black powder during their last visit, about 300 years before "The Hobbit".

Time dilation between parallels has it about 50 years pre-Hobbit for this visit. There has been much discussion about the current location of the One Ring, and it sounds like the 'Let's Go Loot It!' faction of the group may win out.

So, imagine Gollum wearing the One Ring, hunted by assault rifle PCs w/ Hyperspectral Goggles... what would they see?

These optical sensors electronically fuse passive radar, infrared, visual, and ultraviolet imagery into a single falsecolor television image. pg 61 Ultra-Tech

(I understand some fans may be personally offended by the idea of our mucking up Tolkien, but hey it's a wacky game... move along...)

Just looking for fun plot ideas, reasons why the One Ring may or may not work against Ultra-Tech Vision. I know the actual functionality in this situation is purely a GM fiat, but what would *you* do if you were running it. (assuming you'd run this kind of mix...)

and yeah, taking and using the One Ring is going to have BAD consequences if they get that far.
