[ WATCH YOUR FOLLOWUPS! --CDR] 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. -- $anjay $ingh Fire & "Ice" ssingh@watserv1.[u]waterloo.{edu|cdn}/[ca]

I believe you are referring to the Starlight scopes. These use light amplifying image tubes inside, which gather ambient light from stars, the moon, etc., magnify it, and allow you to see in "the dark". The starlight scope is completly passive. It can use infrared light from an infrared flashlight or spotlight as well. There are also infrared scopes, which require and active IR light source. These scopes cannot see ambient light, and using them with a projector will put you at a disadvantage if the enemy has starlight scopes, since they will see your IR emitter, but you can't see anything of theirs. -- Robert Allen, rja@sun.com DISCLAIMER: I disclaim everything.
