Abstract
A method and systems for recovering an image and/or information from a document layer(s) is provided. A first light source directs light to the document. A second light source directs light towards a beam splitting mirror which reflects the light towards the document. An image receiver receives the first and second reflected light from the document layer(s). The image receiver passes a signal to a personal computer which processes the received information. Such processing is to establish whether the document includes a retroreflective laminate, a plain polyester laminate, or neither. Additionally, further processing can establish whether the document has been tampered with, altered, or forged.
