So it's useful if distance to your object changes predictably enough, like in astronomy, satellite imaging and many other kinds of space missions.

- magicalhippo 7y agoWell in astronomy you usually want your telescope to be able to observe different targets. So it depends on the details of how the correction surface has to change when the image-object distance. If it's just a mild deformation and offset, then yeah I guess technology similar to adaptive mirrors could work well.
- oh_sigh 7y agoDistances are usually treated as infinity, at least in astrophotography. I'd be surprised if this secondary lens was able to distinguish between light coming from 1ly and 1000ly
- magicalhippo 7y agoDoh, of course. Not sure what I was thinking.
