    摘要: The method of the invention consists, on the one hand, in serially recording on a tape of photosensitive film a succession of volume holograms each relating respectively to an item of information of a corresponding document to be made secure, each of these holograms being accompanied by an identification and positioning code printed on the same film, in developing and in fixing the holograms thus recorded, and on the other hand in printing at the same time the identity documents with their individual identification codes which are the same as those of the respective corresponding holograms, in adding an adhesive to the holograms after their fixing, and in adhesively bonding together each hologram and the corresponding document after verifying that their respective identification codes match.

    摘要: An identity card or credit card type of card is equipped with a validity-checking device that makes it possible to do away with the use of complementary, sophisticated checking equipment. It results from the association of a structure S.sub.1 comprising at least one layer of piezoelectric material and a structure S.sub.2 comprising a material capable of switching electrically between two optical states (I) and (II) that are different in terms of ocular perception. During the bending of the card, the validity or non-validity of the card can be attested to by the appearance or non-appearance of the validity of the card.

    摘要: The process makes it possible to generate on the basis of discrete preetching elements or flags, the radial tracking error and/or focusing error signals. The flags comprise portions displaced with respect to the mean axis of the tracks to be followed. According to a first variant, each track comprises portions displaced on either side of the axis. According to a second variant the flags comprise portions alternately displaced to one and then the other side thereof. In response to the passages of these portions, windows are generated and the pulses supplied by the photodetectors of the interaction of these portions on the focused scan beam are compared between successive windows.

    摘要: A device for detecting the error in focussing a read-out beam on the impression. Two photodetector cells located respectively in front of and behind the optical axis of the system, in relation to the direction of transfer, produce two electrical signals the difference between which is the read-out signal, a control signal being obtained by a comparison of the phases of the two signals, one of which is phase-shifted so that the optimum focussing point corresponds to zero phase-shift.
