A laser based landmine detector

Research uses lasers to detect landmines, underground objects

Summary:
Enough landmines are buried underground worldwide to circle Earth twice at the equator, but the identification and removal of these explosives is costly and time-consuming. New research could help solve the problem.
So, now as to looking for gold (down under? billy has a go?) :-)

The laser's don't penetrate the ground - they just follow the movement
of the surface of the ground which you have persuaded to vibrate by
other means.
It wouldn't be a great way of looking for gold to mine. A lot pf people
did go to Australian to look for gold to mine in the 1850's.
None of my ancestors did. They had more reliable ways of making their >livings.
The one who got closest to the mine fields was one of my
great-grandfathers, a Methodist minister,
Dr. George Edwards Rowe who
set up a hospital for the miners at Kalgoorlie around 1892.
He'd married a rich woman, so he didn't have to dig for gold himself.

That explains a lot

There are still people from Europe going down under looking for gold
I followed a TV series on German TV, so I would know how and where to look. >Ye never -no

Had other things to do when I was there...
Did not need the cash either.
I did build a sort of metal detector once.
No gold here...
