Three-dimensional images created by laser light that appear to float in space without any physical support.
From Greek 'holos' (whole, complete) and 'gramma' (something written or recorded). The term was coined in 1948 by physicist Dennis Gabor, combining the roots to mean 'whole picture' recorded in light patterns.
Holograms work by recording the light wave patterns of an object—not just what it looks like, but literally how light bounces off it in 3D—which is why they can look incredibly lifelike from different angles, unlike regular 2D photos!
