Garden 3D Hologram

In the United Kingdom, Vodaphone used a 5G network to make a live holographic call. They sent a 3D image of a person standing in Manchester to a VR headset outside of London, where the picture was simultaneously projected onto a stage in front of a live audience. Verizon and Korean Telecom also used a 5G network to enable a Seoul employee to have a live conversation with a 3D hologram of a New York employee.

Light diffraction is used to produce an image in a hologram. A lens is used to focus on an idea, and then the image's light, dark, and colored areas (seen as reflected light) are captured on film or a digital sensor. On the other hand, holography is a type of photography that captures the shape of light waves as they bounce off an object. As light waves collide, they cause interference (in the same way ripples of water interfere with each other if you throw two pebbles into a pond). A hologram is created by recording the light wave interference pattern (a light field).

Although typical holographic images tend to be three-dimensional, they are essentially two-dimensional when displayed on a flat-screen of a computer monitor or projected onto a flat surface like a wall or sheet of glass. To see the projection, the spectator must look directly (or within a narrow view angle range) at the flat surface. Although the picture appears to be three-dimensional, it is a three-dimensional projection rather than a hologram.

Creating 3D holograms, "in which a 3-D scene is encoded in terms of optical diffraction, transformed into the fringe patterns of the hologram, and then converted into a signal for a spatial light modulator (SLM) and projected in real-time," turns out to be a difficult task. 2 Princess Leia has driven artists for the past 40 years to try to build genuine 3D holograms that can be projected into thin air—also known as "volumetric images"—that can be viewed from all sides and have 360-degree visual dimensionality.

The industry is also dealing with the challenges of producing computer-generated content that can be displayed in 3D holographic format, in addition to the optical challenges of capturing and projecting 3D holograms taken from real-world photographs. Mathematical models of 3D objects, such as point cloud and polygon-based algorithms, can be used, but they impose a significant computational burden on any holographic projection system.
