Holograph vs. Hologram — What's the Difference?
By Tayyaba Rehman — Updated on December 24, 2023
Holograph is a document written entirely in the handwriting of the person whose signature it bears. Hologram is a three-dimensional image formed by the interference of light beams from a laser or other coherent light source.

Key Differences
Holograph refers to a document written entirely by hand by the person who is authorizing or creating it. It often relates to legal documents like wills. Hologram, in contrast, is a term used in physics and photography, referring to a three-dimensional image created with photographic projection.
A holograph is characterized by its personal nature, as it is handwritten by the individual involved, making it unique and often used for authentication. Holograms are technical products created using light interference, resulting in a visual effect that appears three-dimensional.
In historical contexts, holographs were significant for their authenticity, as they were direct handwritings of notable figures. Holograms are a modern technological feat, used in various applications ranging from security to entertainment.
The creation of a holograph requires no more than a writing instrument and paper, emphasizing the personal effort and authenticity. The production of a hologram involves complex processes involving lasers, mirrors, and photographic techniques.
While holographs are associated with legal and historical documentation, holograms are often associated with advanced imaging technology, including security features on credit cards and artistic displays.

Holograph
A handwritten document that is solely the work of the person whose signature it bears, especially a letter, deed, or will; an original manuscript, a protograph.
Hologram
A photographic image giving the observer a seemingly three-dimensional view of the represented object. The three-dimensional effect is produced by exposing a photographic recording medium to an interference pattern generated by a coherent beam of light (as from a laser) reflected from the subject, interacting with a beam directly from the source. The full three-dimensional effect requires illumination of the image with coherent light, but less perfect three-dimensional visual effects may also be observed when the hologram is illuminated with white light.
