    摘要: In connection with a method and a device for the control of the optical alignment of two lightwaves in the course of a coherent superimposed reception a spatial beam regulation is achieved in that the light of a local laser (5) is superimposed on the received light (1), that then the signal obtained in this manner is divided into two identical beam portions (1A, 1B) by means of a beam splitter (2) and that a respective error signal (14, 16) is generated from the two portions by means of a respective detector arrangement (3, 4), so that the two error signal portions result in a spatial error signal. The original data signal (15) is again obtained by the addition with the correct signs of the error signal portions.

    摘要: A system for operating a laser transmitting system for optical space communications, in particular in combination with the generation of amplified laser light under space conditions. The optical laser transmitting system here consists of a laser 2, acting as an optical oscillator, and an optical semiconductor amplifier 6 which are connected with each other by a polarization-maintaining optical fiber 4, or alternatively by an optical space connection. A light beam 8 exiting from the optical semiconductor amplifier 6 is converted via a special optical lens system 10 into a collimated light beam 12 with an even lateral extension and is radiated after further optical conversions.

    摘要: The system for the optimization of inter-satellite links has a terminal comprising a multiplexer (1) which is connected to the output of a transmission unit (2) and has a subchannel input that is connected to an evaluation unit (3). The terminal also has a demultiplexer (5), which is connected to the input of a receiver unit (6) and has a subchannel output that is connected to an optimization unit (8). With the aid of an auxiliary channel established through the multiplexer and demultiplexer in addition to the transmission channel present for user-information data, it becomes possible to transmit operation-internal data pertaining to at least one continually measured parameter to the optimization unit of the opposite terminal via the evaluation unit (3).

    摘要: The directional reception of extremely weak light signals without diverting a portion of the signal light into separate detectors for the purpose of obtaining an alignment signal is caused by the arrangement of several detector means (X, Y) which, when unmodulated light is superimposed on them, generate electrical output variables (x1, x2, y1, y2) which, after they have been added in a network (I), result in an information signal which, when it is linked by multiplication with several difference signals (x, y) formed in the network (I), converts them into narrow-band signals, which reproduce an alignment error.

    摘要: The invention relates to a method and a device for distance measuring between two stations (A1, B1) connected by a communication channel. The method is based on a command structure, wherein the satellite (A1, B1), by means of which a distance is to be determined, sends a range request (3) via an inter-satellite communication channel to the other satellite (A1or B1), which thereupon acknowledges this range request (3) with an answer (4). The distance is determined from the corresponding measurement of the cycle time. The range request (3) and the corresponding answer (4) are transmitted in a multiplexed communication channel.
