Hologram document recording system - secures register material firmly to document and uses reflected ray interfering with reference ray

摘要

The system provides confirmation of identity by recording the hologram from an identity document such as a credit card onto a register, using a reference ray and one from the document. In front of a holograph insulator, the photo-sensitive register is firmly fixed to the document. The document ray, reflected from it, is directed to the register, where it interferes with the reference ray, so as to form the hologram of data to be memorised. The hologram can be developed without the registration material being separated from the document. The material can be placed in a window formed in the document.
