A number of photorecon satellites do exactly that, according to Dino
Brignoli, a retired senior CIA recon expert who has a rather interesting
"road show" on photoreconnaissance and history. I heard him a few
years ago at the Washington chapter of the Society for Photographic
Scientists and Engineers.
He said that one of the major breakthroughs in imaging satellites,
which was classified for some time, was using moving backs both
to cancel motion and allow much longer exposure times.
