A classic hologram is usually made using a 3D object, often a model. A laser beam is split in two and part is diverted onto the object, reflected off it then allowed to combine (or interfere) with the other part of the beam known as the reference beam. The classic hologram is a recording of the interference pattern between the object and reference beams. A well-known example of a classic hologram is the dove used by Visa on their credit cards.
