I thought this paper (https://accelconf.web.cern.ch/accelconf/p05/PAPERS/WOAC001.PDF, published by a group in Berkeley's Lawrence Laboratory!) is a pretty interesting discussion of aberration correction for a very specific domain of cameras, the electron microscope! I didn't read through the whole thing, but a general tldr is that the authors used "electron mirrors", an element at a microscopic level, to perform correction, an application of the diagram on the left at a really, really small scale!
