That may be true but a Google of "880nm 890nm LEDs" gave quite a few hits.The most common wavelengths available are 850nm and 940nm. The 850nm is slightly visible to human eyesight.
Do you have pictures of that?Sony's first "night view" camera caused trouble because it could see the frequencies of "heat" and therefore looked through clothing.
People's "hot zones" were clearly visible.
Do you have pictures of that?
I believe that's mostly an urban myth, since the IR radiation from the body does not penetrate clothing to any significant amount. It's the temperature of the clothing that you see. I worked on a military FLIR system which operated in the the IR region around 10 microns which is most sensitive to objects near room temperature, and a view of a person only showed their clothing and exposed skin temperature. The clothing was, of course, warmer where it directly contacted the body, but no details beneath the clothing were visible.
One interesting observation was that you could see the inside of a person's nostrils get lighter and darker as the person breathed in and out.
The clothing that the Sony camera looked through was extremely thin bathing suits. Maybe the kind of cloth that allows the wearer to still get a suntan while wearing it.
My new eye lenses after cataracts surgery see thru bathing suits. (smilie)
The new lenses inside my eyes are plastic with UV protection so I don't need sun glasses. Very sophisticated tests allowed the manufacturing of the lenses to make my distant focussing absolutely perfect so I can see the details on pretty young ladies very far away. Yum.
The close-up vision is the same as my original lenses so I use the same reading glasses I had before.
For a few thousand dollars more I was offered synthetic lenses that have adjustable focussing for near and far. But they are poor at night and sometimes get "stuck". I am very happy with my new lenses.
Canadians have excellent health care. It is mostly paid by income taxes.Did you have to go to the States to get the implants? The anti-Obama crowd down here would have us believe the Canadians have the worst health care in the world (because it is government run)![]()
