Kim, as far as scanning photons, it violates Heisenberg uncertainty principle, it is a least a very poor wording, at worst a fatal flaw. You can scan a beam (of photon, electrons particles whichever, you cannot scan the particles or photons themselves, look it up in the dictionary).
As for the second comment on depth information, one VRD cannot give any depth information (unless you use the same VRD to illuminate both retinas sequentially, which is not what the claim covers), period. The photons either hit the appropriate rods and cones or do not. Focusing helps with image resolution not depth perception, it is as simple as that.
