I was hoping to see some sort of atomic-scale structure that shifted the frequencies of a tiny amount of infrared light just enough for our visual system to pick it up.
That's almost what it says it does. I think you took the word filter too literally.

It sounds like it might display the image on a thin screen rather than shift the light into the visible spectrum, but it was light on details.
That's an amazing sci fi dream becoming reality.
