An expanding superintelligence sphere acts as a lightyears-wide optical lens, providing extremely redundant observations of far-off objects. This can be combined with superintelligent error-correction and image reconstruction. If you have multiple such superintelligences then you get even more angles. But yeah, I haven’t done the actual calculations; it’d be super cool if someone else did them.
On another note, about six months ago I spent a few days looking at the quantum information theory literature trying to figure out if AIs could coordinate to reverse the past; I think I have enough knowledge to pose it as a coherent question to someone with a lot of knowledge of reversible computing and QIT. I’d like to do that someday.
But the “error correction and image reconstruction” itself is not lossless. There is inevitable distortion caused by scattering off the unknown distribution of interstellar dust particles and from gravitational lensing between the AI and its target. Not to mention all the truly random crap happening in the interstellar void as the photons interact with the quantum foam. The inversion methods you suggest do not yield a true image, merely a consistent one.
It could still be enough to resurect a person, if the difference from truth is on the order of the difference between me right now and me after sleeping for a few years. (Hint: the two me’s are very different, but they’re still recognizable as me.)

I’m not a total expert, but try me.
I’ll have to spend a few hours reloading the concepts into my brain. When I do that I’ll post it to Discussion.
