I think there is a misunderstanding, perhaps on my part, of what
is being "imaged". Can we go back to that and describe what is meant
to make sure we are on the same page? I thought we were talking
about an almost literal "image" in the sense of optics and light,
except using sound to convey the information, and that we would
end up with a "picture" on a screen. In that sense I see each pixel,
for example, representing the intensity of sound in a specific
direction, just as in a picture each pixel represents the brightness
in a specific direction.
BTW, could you please leave the crossposts on the followup? It
appears you are hailing from sci.physics, but since the OP
crossposted, there are now participants from other groups such
as myself. I know there are arguments against crossposting, but
since it's been done we might as well leave it in order to keep
the conversation from breaking up.
