Optical free-space communication

It is claimed a method for the transmission of at least two optical signals to at least two receivers, preferably comprising a source, an alignment module, one telescope and at least two receivers, whereas the source generates two or more optical signals, and whereas the first optical signal is guided on a first beam path from the source via the alignment module and the one telescope to the first receiver and the second optical signal is guided on a second beam path from the source via the alignment module and the one telescope to the second receiver. According to the invention the one telescope has a field of view in which the at least two receivers, at least a first receiver and a second receiver, are located, and that the at least first and/or second beam path is aligned in the be alignment module in order to steer the first optical signal via the one telescope to the first receiver and in order to steer the second optical signal via the one telescope to the second receiver.
