A hologram is a three-dimensional image created using light and laser technology to record and reproduce the appearance of an object. Unlike traditional photographs, which capture a flat, two-dimensional representation, holograms can display depth, texture, and perspective, allowing the viewer to see different angles of the object as if it were physically present. This is achieved through the interference of light waves, which are recorded on a special surface, such as a holographic plate or film. When the hologram is illuminated by a light source, it reconstructs the original light pattern reflected by the object, creating the illusion of a 3D image. Holography has applications in a wide range of fields, including art, security (such as on currency), medical imaging, and data storage. Its ability to provide a more lifelike representation of objects makes it a powerful tool in both scientific and commercial sectors.
