The invention relates to electronic data carriers having non-volatile memory, and to a method for short-range optical communication. The aim consists in creating a simple, compact, jam-resistant data carrier and a data read/write device. A primary source of radiation is placed in a first device, and a second optoelectronic device is used in a passive mode, in which it receives power as a result of photovoltaically converting the energy of an absorbed portion of the radiation from the first device and responds to a query from the first device by means of modulating a reflected portion of the radiation. The devices are brought into contact in such a way that a light guide is formed between an active structure of the first device, i.e. an optical transceiver, and an active structure of the second device, i.e. a target, said light guide concentrating radiation in a communication channel between the devices.
A method of short-range communication between two optoelectronic devices interacting by the principle Master-Slave (hereinafter referred to as M-S), based upon that the primary emission source is only placed into the first, M-device, and the second, S-device is used in passive mode at which it receives power resulting from photovoltaic conversion of energy of the absorbed part of the primary (incident) emission being sent by the M-device at request of the S-device, and in its turn, responds the request through modulation of the secondary (reflected or in other method returned to M-device) part of its emission, WHEREIN to accomplish data exchange between the devices in accordance with the established protocol, both devices are brought to touch in the way that between the active structure as part of the M-device, the optical transponder, and the active structure as part of the S-device, the target, the optic guide be formed concentrating emission in the communication channel between the devices and limiting its distribution into the environment, upon which on the start command being generated by the M-device, the data exchange is accomplished, in that as the target in the S-device there is used the functional area of the reversing (reversible) optoelectronic instrument capable of working both as the receiver (energy converter) of the primary emission and as the electrically controlled transmitter (modulator) of the secondary emission.
An optoelectronic data carrier (hereinafter referred to as ODC) being the recorder/reader (hereinafter referred to as REC/READ) receiving repeater, receiving its power as a result of photovoltaic conversion of energy of the emission being sent by the REC/READ at request of the carrier and responding the request through modulation of the secondary (reflected or in other method returned to the REC/READ) emission, WHEREIN it is made in the form of a hybrid micro-assembly comprising the silicon integrated circuit (IC) with the circuit boards of non-volatile memory to which there are connected in the form of closed circular circuit the optically active diode structure of material, for example, of A3B5 group allowing it to work both in photodiode (converting) and in light-emitting diode (LED) (emitting) modes, and the inductance cell (microcell) the inductance of which is determined by the criterion of sufficiency of energy accumulated in its magnetic field for one current pulse, for formation of the response pulse of light being emitted by the structure in LED mode upon ending of the brightening pulse due to the fact that current cannot cease immediately in the circuit with inductance, at that the IC comprises the electronic key disconnecting the mentioned circuit in cases when the binary digit of the digital sequence being transferred to the instant interval is such that formation of the response pulse is not required.
An ODC being the REC/READ receiving repeater receiving its power as a result from photovoltaic conversion of energy of the emission being sent by the REC/READ at request of the carrier and responding the request through modulation of the secondary (reflected or in other method returned to REC/READ) emission, WHEREIN it comprises the non-volatile memory circuit boards and the optically active structure operating solely in photodiode (converting) mode, and at least one further structural and/or circuitry component ensuring modulation of emission reflected from the diode structure, at that of all the above mentioned components, at least the non-volatile memory circuit boards are implemented as part of the silicon IC.
A REC/READ comprising the optical transponder sending the primary emission to ODC at its request and receiving the secondary (reflected or in other method returned to REC/READ emission from ODC at its response and the system of request and response signals' separation, WHEREIN it comprises common for transmission and receipt modes optically active diode structure of material of, for example A3B5 group, allowing it to operate both in LED (emitting) and in photodiode (converting) odes, and the electronic system of time separation of request and response signals in the form of a switch box connecting alternatively the optically active diode structure to the request signals amplifier output or to the response signals' amplifier input.
The REC/READ comprising the optical transponder sending the primary emission to ODC at its request and receiving the secondary (reflected or in other method returned to REC/READ) emission from ODC at its response, and the system of request and response signals separation, WHEREIN it comprises the optical system of spatial separation of request and response signals in the form of a stretch of the rigid fibre optic box being the bundle of laid in parallel fibre optic guides, which is sharpened and/or rounded on its external end, and on the internal end, comprises the shank of cross-section smaller than cross-section of its main part—such that it would only accommodate the core intended for channelling of the primary emission, and the butt-ends of peripheral fibres intended for channelling of the secondary emission would be in the zone of step-wise transition from the main part to the shank, at that the shank is passed through the hole in at least one mirror tiled relative to optical axis in the way that peripheral fibres' butt-ends would be displayed to the photo perceptive surface of at least one receiving (converting) instrument of the transponder installed opposite to the mirror near the fibre optic box, and the transmitting (emitting) instrument of the transponder, a LED or a laser, is installed on the shank butt-end put outside the mirror (system of mirrors).
