Abstract
A device and method for mass producing reflection holograms. Photosensitive material is drawn across an object to be copied and coherent radiation is scanned across the material and the object. The object may comprise a component which is variable, such as a counter, or a hologram. The exposed photosensitive material is removed from the object, the symbols on the object are changed if desired, fresh material is moved into place, and a new hologram is created. The holograms of the present invention preferably have the capability to be sequentially or individually numbered or otherwise customized with a variety of symbols, for example for security purposes.
