DOCUMENT SECURISE, SYSTEME DE FABRICATION ET SYSTEME DE LECTURE DE CE DOCUMENT

摘要

The invention concerns a document comprising at least a drawing or an information produced, for example, by printing. Said document further comprises a hologram representing part of the document. The hologram of the document is recorded by a system comprising a pre-recorded or electrically controllable optical modulator (23) wherein is recorded the image of part at least of the document. Said modulator is designed to be associated with a photosensitive material film (21). A first reference wave (R) illuminates the photosensitive material film. A second incident wave (I) on said modulator (23) and producing a third object wave (O) is also transmitted with the photosensitive material film to interfere in said film with the reference wave (R).
