From: <ssingh@watserv1.waterloo.edu>

I was wondering if someone could explain to me how those devices
used in the Gulf War allows soldiers to see in the dark.

How do they work? Do they emit something and then process returned
signals like sonar? Or does it only absorb infra-red radiation?

And if you can recommend a book that explains how it works, I'd
really appreciate it.

Thanks.
