tl;dr: if you could build a tiny array of nantennas, could you use it to form an image?

My inspiration for this idea comes from insect compound eyes as well as some uses of optical fiber like boroscopes and endoscopes, where light enters a dense array of optical fibers and emerges as an image on the other end.

The idea is that you have a densely packed array of nanoscopic antennas that are resonant at visible wavelengths, with each antenna connected to its own “feed line” which all in turn connect to a receiver that can collate the received signals from all the antennas into an image.

    I don’t see why not presence sensors like what are used in offices or home automation are based on like 60 gigahertz radio frequency and that’s fine enough to tell when a person breathes in the room.
