Re: RE: [PSUBS-MAILIST] Blue-green laser
The designs discussed in this thread all sound great.
i did amateur astronomy for some time, and a couple of things from there may improve the designs.
light collection is the objective in astronomy, not magnification. the problem is not dissimilar. underwater is actually a low light situation (in most cases). by mounting telecope style mirrors as the collectors, you should achieve far greater visibility.
likewise, the image enhancers (photo multipliers) used in astronomy could amplify existing light (laser or ambient) and catch some light from the laser scattered to other wavelengths underwater. hunters' night vision goggles work by the same principle and either hobby could be used to source parts. the astronomy sources however may offer the best mix and match of interchangable parts.
instead of projecting images onto the hull, although this has many advantages and would look very kewl, VR goggles and work in this field may also yield some off-the-shelf software.
hope this helps
cheers

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

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.
