Explain the application of wave optics in holog... - SS2 Physics Optics - Wave Optics Question

Holography is an imaging technique that utilises the interference of light waves to create three-dimensional images. A hologram is formed by recording the interference pattern between a reference beam and an object beam on a photosensitive medium. When a laser beam is shone onto the hologram, it reconstructs the original wavefronts and creates a three-dimensional image of the object. The essay should explain the process of holography, including the recording and reconstruction stages, as well as discuss the various applications of holography, such as security holograms, holographic displays, and holographic data storage.
