What Does Hologram Mean?
A hologram is a recording of light wave interference patterns that can be played back to create a high-resolution image in full color and three dimensions. Unlike the stereoscopic technologies used to create 3-D experiences today, holograms do not require special glasses.
Techopedia Explains Hologram
In 1951 Dr. Dennis Gabor won the Nobel Prize for inventing and developing the holographic method after he discovered a way to produce images that had the illusion of depth. Dr. Gabor’s method was based on his observations about the interaction between light waves (interference) and how light waves align in phase with one another (coherence).
