Would a visible light beamforming "telescope" be feasible?

If you had a phased array of high speed photodiodes that were spaced sufficiently far apart, would it be possible to apply beamforming theory to create a steerable visible light "telescope"? … Difficult, huge amount of data...but it doesn't seem impossible unless I'm misunderstanding how beamforming works? …
