Pardon my ignorance, but was this the secret behind those infamous
X-ray vision
glasses that used to be advertised in the back of comic books?

And how do you get IR sensitivity in a passive device? A single IR
photon can't
produce a visible photon by fluorescence. Can you have unstable chemical bonds
triggered by IR photons?


The CCD sensors in the video cameras have pretty good IR sensitivity.
Filtering out some/most of the visible gives you these 'unusual' images.
