Ok...I didn't want to restart this particular thread, but it seems there
is still enough confusion to warrant it.

1) Thermographics convert radiated heat to a visible spectrum.

2) InfraRed is any light below visible (to a human) red (just like
ultra sonic is any sound above what a human can hear)

Most current night vision devices cover a broad band of light from IR
through UV light. They basicly widen the spectrum of light you can
see and enhance the image.

The basic physics of the two types of devices are completely
different as is the way they 'see.'

I can get further into this is anyone wants, but this has been beat
to death.
