摘要： The invention relates to a radial slaving method and to a reproduction device implementing it for optical discs.In an optical head of a conventional reproduction device using a four-quadrant detector with four photodiode is distributed on either side of a direction parallel to the axis of the track, the individual signals of the photodiodes (d1 to d4) are combined in order to obtain read signals along the two diagonals (diag1, diag2) by subtraction (21, 22).A phase comparison signal circuit (100) makes it possible to construct a radial error signal (Sr) by measuring the phase shift of the diagonal read signals.The invention applies in particular to phase discs with slightly phase-shifting marks.

摘要： The invention concerns a recording medium for optically readable data of the multilayer type, a method for making same and an optical system for reproducing said data for reading the medium.The medium (Sb) comprises a stack of layers (C1 to CN) whereof the interfaces constitute planes (P1 to PN) bearing slightly phase-shifting information elements. Said planes generate a relatively significant disturbance of the transmitted beam while diffracting only a very small part of the light passing through them. The reading beam (FI) is focused on the bearing plane and reading is performed by transmission. The disturbances caused by the neighboring defocused layers are eliminated by far field detection of only the low spatial frequencies in the transmitted beam.The invention is particularly useful for very high capacity data optical storage.

摘要： A quantum encryption device comprises a transmitter and a receiver between which an encrypted piece of information is transmitted. The transmitter comprises at least means to send a first packet of photons and an information photon to the receiver, the appearance of the information photon following the packet being lagged by a period of time &tgr; according to a law of probability. The transmitter also comprises means for the encoding of the information photon. The receiver comprises at least means for the encoding of a second packet of photons coming from the first packet and substantially lagged by the period of time &tgr; with respect to this packet, and interference means to make an information photon interfere with the second packet of photons. These interference means provide a packet of photons to create a quantity of photons substantially equal to ±2 times the variance of the noise due to the second packet. The invention can be applied to the industrial-scale making of encryption systems.

摘要： An anti-piracy recording disk. The disk includes a main recording track which has interruptions or changes of turn. This gives rise to non-sequential reading and therefore to information which is difficult to access. The copying of such a disk by conventional means is very difficult making it possible to easily detect counterfeits or to render any copy unusable.

The object of the invention is a read-out system which ensured focussing and tracking by the synchronous detection of positional errors with the help of a read-out beam one of the halves of which is intercepted by a half-wave plate; an oscillatory motion is imparted to the read-out spot in the plane containing the track.
