Abstract: A method for the redundant transmission of data by means of light-based communication may include a data stream to be transmitted that is converted into symbols. This data stream is converted from bipolar symbols into multiple partial data streams having e.g. unipolar-positive symbols. The partial data streams are converted into multiple semi-redundant signals that are then transmitted to the receiver via multiple light-based channels. In the receiver, the received signals are converted back again analogously to when they were sent, in order to obtain the original data stream again.

Abstract: A system may involve transmitting data via a light-based data link. The aim of the invention is to establish a data connection which is as simple and efficient as possible. In order to achieve this, the system comprises various components which deflect the light containing the data and distribute it in a targeted manner. The invention also relates to various fields of application for the system, such as mechanical joints and robot joints, rail systems and luminaires.

Abstract: Embodiments provide a light detection system including a detector configured to provide a received light signal and a processing circuit configured to provide a plurality of branched signals, each being representative of the received light signal and each being time delayed to one another and with respect to a non-delayed branched signal, wherein a delay period between the plurality of branched signals is smaller than a duration of the received light signal, and wherein the delay period between the plurality of branched signals is chosen such that peaks of the branched signals overlap in time and to sum up the plurality of branched signals including the non-delayed branched signal with one another to provide a combined signal, wherein the plurality of branched signals differ from one another in such a way that, as a result of a summation, respective signal components of the plurality of branched signals combine in a constructive manner and respective noise components of the plurality of branched signals combine in an at least partially destructive manner.
