Holograms works based on the holographic principle, it is a physical structure resulting from the diffraction of light to create multiple wavefronts, which together assemble to create a 3D simulation of an object.

Holograms operate from any angle, allowing the viewer to view them from any location. Unlike other technology, a real hologram uses a high-resolution holographic display to send light through a multi-layered piece of polymer known as a phase guide that steers and focuses the light into mid-air. This essentially creates a holographic object that moves refracts and reflects in physical space. In other words, it’s a 3D image that can be projected onto mid-air.
