How is VLBI delay calculated?
This is impossible to answer without clearly defining the geometry of your setup. VLBI delay and delay rate are calculated assuming the source is a long way away. This essentially means the incoming s …

Would "layered" radio interferometry work?
Note the first stage would be treated as beam forming - you cannot do interferometry between the first stage and somehow do interferometry between the results. … Ie the first stage is summing the voltages (with appropriate phase corrections) and the second stage would be interferometry. …

Is Optical VLBI theoretically feasible? If not why not?
In principle yes this should work. Optical telescopes separated by 1000 km would "see" the same photon. Why would this be any difference for radio waves with a few cm to few mm wavelength compared to …
