RE: [PSUBS-MAILIST] Blue-green laser (was: Empress of Ireland)
Stephen,
What
kind of data would you need. As far as real time goes, at the speeds we
are travelling underwater .5 seconds to 1 second might be okay. It takes a
bit for these vehicles to respond any way.
I used to work in a cardiology
department. There has been much work using ultrasound to create 3D
images of the heart. Similar systems are used for oil exploration.
I have worked with the reconstruction algorithms. It is not that
difficult. I'd volunteer to work on it if someone provided me with
useful data.
You don't need sophisticated custom circuitry or DSPs if
you are not picky of how fast your image
refreshes.

You can use reconstructive sonar to create a detailed
3D
image of your surroundings. The problem is that
this
is just out of
the reach of all of us at this time. If
someone publishes the
reconstruction algorithms I
might
be willing to give it a shot. So far
only the US
military has done this work extensively.
Naturally
they
aren't releasing any usefull
data.
