What it is
The recording of the amplitude and phase of light to reconstruct a three-dimensional image. Impractical until the laser, it now protects cards and banknotes and is used in metrology and storage.
What it led to
- Security holograms on cards and banknotes
- Holographic interferometry in engineering
- Holographic displays and augmented reality
