RE: [PSUBS-MAILIST] Blue-green laser (was: Empress of Ireland)

I think the range is the key, because high-freq active sonar will give you a
decent view but not very far, and a blue-green laser would sharpen up the
image and has a little longer range, then combine it with passive sonar
which, if in a sound channel could be heard from Hawaii to California.  So
combining all of those in puts and number crunching in a computer, I would
think would give some good data.  How practical and cheap it would be, at
this point is anybody's guess.  If it could be made from off the shelf
technology all the better.

Depends on how far ahead of the sub you can get readings.  If you can
get a projection at least 50' to which ever side you have the transducer
on, keep it stored in computer memory and you should be able to project
your course on there.  Or am I in the left field again?
