Holography is a theoretical framework based on interference phenomena that records and reconstructs complex electromagnetic wavefronts by capturing both amplitude and phase information relative to a reference beam. The core mechanism relies on the superposition of object and reference waves creating an intensity distribution proportional to their cross-correlation, which encodes three-dimensional spatial coordinates via constructive and destructive interference patterns. This concept belongs to Optics as a sub-discipline demonstrating that a two-dimensional boundary condition can fully constrain light field propagation in three-dimensional space through linear wave equations and diffraction theory.
