- ge96 2y agoYeah I know they can map cities, was thinking about scanning the sky, probably dumb/doesn't make sense but yeah
- itishappy 2y agoNot a dumb question at all, it can work from space! I think getting enough return signal and contrast will be the main issues. Both can be solved with a big enough lens, but then cost and maintenance will become an issue. If the system can be optimized beyond needing a single lens per beam than it might be feasible!
