Re: RE: [PSUBS-MAILIST] Blue-green laser
I personally would like to display this type of data
on an LCD. I don't want goggles over my eyes in this
situation, and I have seen the problems with getting
a projection system to perform. Light amplification
is a great idea though. It would be nice to be able
to see using a few different methods, so that adverse
conditions don't douse your campfire.

That would be the start of it and could progress from
there.Any suggestions on how to make something like
that. Tim R. -----Original Message-----

Tim,
Your projection idea seems to be describing
something similar to the Heads Up Displays used in
aircraft (military planes and commercial jetliners)
and even some new cars. Actually, it's also like
what is used in a Teleprompter at TV stations.
