Technically speaking, a hologram is a photographic recording of a light field used to display an object with its true dimensions. To put it in layman's terms, it is the 3-Dimensional replica of an object in real time using light interface technology without the need for special 3-D glasses or any other intermediary. The potential of holography is enormous when it is interspersed with other technological advances in various walks of life. Be it entertainment, security or education, the diversified benefits of holograms are revolutionary and far reaching.
Let’s take up the case of security. To keep anti-social tempering of confidential and financial transactions at bay, bills, identity card, credit cards and the likes have holograms imprinted on them. Regular holograms encode three-dimensional image in a two-dimensional surface, as in the case of hologram on a credit card, thereby preventing counterfeiting.
