holographically

Holographically refers to something pertaining to or resembling a hologram. A hologram is a three-dimensional image created by a technique that uses light waves to record and then project an image. This recording process involves interfering two beams of light, one of which is reflected off the object to be recorded, and the other acting as a reference beam. The resulting interference pattern, when illuminated correctly, reconstructs the light waves that originally emanated from the object, creating the illusion of a three-dimensional image.

When something is described as being holographic, it implies it possesses qualities associated with holograms, such as depth, parallax, and the appearance of being a physical object that can be viewed from different angles. This can apply to visual representations, data storage methods, or even conceptual ideas that mimic the layered and information-rich nature of holographic projection. For instance, holographic displays create images that appear to float in mid-air, offering a truly three-dimensional visual experience without the need for special glasses.

The term holographically can also be used metaphorically to describe systems or information that are distributed and redundant, much like a hologram where each part contains information about the whole. This decentralized nature means that even if parts of the system are damaged, the entire information can still be reconstructed. In scientific contexts, it is used to describe phenomena or techniques that employ holographic principles for recording, reconstruction, or analysis.
