Understanding Holography and Holograms by Mamta Mantri Chokhra is a document available to read on EtoBox.
Holographic images allow users to view objects like engines from the inside in 3D by recording both the intensity and phase of reflected light.

When illuminated by laser light, the hologram reconstructs the 3D image without using lenses. Common uses include security features on IDs and credit cards that change appearance when move
