A holographic storage network is a system that uses holography to store and retrieve data in three dimensions. Holography is a technique that creates holograms, which are images that preserve the depth and perspective of the original objects. A holographic storage network splits a laser beam into two beams: a reference beam and a signal beam. The signal beam carries the data and passes through a device that modulates the light. The reference beam and the signal beam interfere with each other and create a hologram that is recorded on a storage medium. To read the data, the reference beam is shone on the medium and the hologram is reconstructed.
