Ah yes, of course, I see what you mean. Presumably there is some minimal number of pixels required to stand any chance of resolving the orientation of a particular bundle of light rays (I would imagine 3)? Also, would it be true to say that the more pixels you manage to spread a given ray bundle over, the better the reconstruction, and that the main trade-off is between the accuracy and the density of the reconstructed ray bundles, for a fixed number of pixels?
