The holographic waveguide clones this pupil many times, allowing the eye to view the whole image from a number of different locations.

Does the military use holograms?

1. Military mapping. Geographic intelligence is an essential part of military strategy and fully dimensional holographic images are being used to improve reconnaissance. One American company has delivered over 13,000 3D holographic maps of “battle-spaces” for the US army.
