Holography is a 3D imaging technique that uses lasers to record light patterns from an object and recreate its dimensions and depth when viewed from different angles. It can render subjects with complete dimensional fidelity, appearing so real that viewers want to touch them. Recent advances in holographic technology allow for projecting lifelike 3D moving images of people for presentations, entertainment, and virtual meetings without needing to travel. However, fully realizing the potential of holographic communication will require more advanced computers and internet infrastructure.
