Key Terms

Hologram
A three-dimensional image created by recording light patterns.

Example: The hologram on the credit card prevents counterfeiting.

Interference
The phenomenon where two or more light waves overlap and combine.

Example: Interference patterns can be seen in soap bubbles.

Diffraction
The bending of light waves around obstacles or through openings.

Example: Diffraction patterns are used in various optical devices.

Light Field
A representation of the intensity and direction of light rays in a space.

Example: Light fields are used in advanced imaging techniques.

Recording Medium
The material used to capture holographic images.

Example: Photographic film is a common recording medium for holography.

Reconstruction
The process of recreating a holographic image from the recorded data.

Example: Reconstruction allows us to view the 3D image from different angles.
