Claim 1
Independent Claim
288 words
A system for the transmission of information between an inquiry station and a response station, wherein the inquiry station includes an optical radiation means for transmitting an outgoing signal and for subjecting this outgoing signal to a modulation in fixed pulse rate and at a separate time with an information code, the optical radiation means also coding the outgoing signal with an indication of an end of a transmitted message, wherein the response station includes a means for receiving and evaluating the outgoing signal, a means for subjecting to a modulation and reflecting back the outgoing signal as a return signal, and an enabling means for controlling an enablement of the reflecting back means in-dependance on an evaluation by said receiving and evaluating means of the indication of the end of the transmitted message contained in the outgoing signal, characterized in that (a) an initiation of said enabling means is controlled by the evaluating of the indication of the end of the transmitted signal by said receiving and evaluating means, (b) at the initiation of the return reflection, an acknowledgement signal is transmitted by said reflecting back means of said response station, (c) by use of the acknowledgement signal, a control means for switching said radiation means of the inquiry station to at least one of a fixed pulse rate and a fixed coding of the outgoing signal is controlled, and (d) at the response station, said receiving and evaluating means includes a means for recognizing the at least one of the fixed pulse rate and the fixed coding of the outgoing signal and for actuating a modulator tuned to a fixed pulse rate in order to appropriately modulate the return signal produced by said reflecting back means.
Claim 2
Independent Claim
288 words
A system for the transmission of information between an inquiry station and a response station, wherein the inquiry station includes an optical radiation means for transmitting an outgoing signal and for subjecting this outgoing signal to a modulation in fixed pulse rate and at a separate time with an information code, the optical radiation means also coding the outgoing signal with an indication of an end of a transmitted message, wherein the response station includes a means for receiving and evaluating the outgoing signal, a means for subjecting to a modulation and reflecting back the outgoing signal as a return signal, and an enabling means for controlling an enablement of the reflecting back means in-dependance on an evaluation by said receiving and evaluating means of the indication of the end of the transmitted message contained in the outgoing signal, characterized in that (a) an initiation of said enabling means is controlled by the evaluating of the indication of the end of the transmitted signal by said receiving and evaluating means, (b) at the initiation of the return reflection, an acknowledgement signal is transmitted by said reflecting back means of said response station, (c) by use of the acknowledgement signal, a control means for switching said radiation means of the inquiry station to at least one of a fixed pulse rate and a fixed coding of the outgoing signal is controlled, and (d) at the response station, said receiving and evaluating means includes a means for recognizing the at least one of the fixed pulse rate and the fixed coding of the outgoing signal and for actuating a modulator tuned to a fixed pulse rate in order to appropriately modulate the return signal produced by said reflecting back means.
Claim 3
Dependent Claim
25 words
System according to claim 1 wherein said acknowledgement signal is an unchanged reflection of the end of a transmitted message coding of the outgoing signal.
Claim 4
Dependent Claim
91 words
System according to claim 2 wherein said optical radiation means includes a plurality of laser diodes in which each laser diode (2 1 -2 n ) is connected to one end of an optical fibre 21 1 -21 n ) whose other end is combined to form an optically homogeneous integrator body (23) characterized in that to increase the pulse repetition rate the individual laser diodes are not all driven simultaneously but rather sequentially in discrete groups of at least one said laser diode, and which groups are driven in succession.
Claim 5
Dependent Claim
39 words
System according to claim 2, characterized in that the inquiry station includes a response station and the response station includes an inquiry station such that an information exchange in both directions is possible in the manner of alternate operation.
Claim 6
Dependent Claim
88 words
System according to claim 4 wherein said optical radiation means includes a plurality of laser diodes in which each laser diode (2 1 -2 n ) is connected to one end of an optical fibre (21 1 -21 n ) whose other end is combined to form an optically homogeneous integrator body (23) characterized in that to increase the pulse repetition rate the individual laser diodes are not all driven simultaenously but rather sequentially in discrete groups of at least one, and which groups are driven in succession.
