<p>The present invention relates to an optical receiver (1) for receiving useful alternating-light signals and for storing electrical energy obtained from extraneous light, comprising a photodiode (2) for receiving light, which comprises extraneous light and a useful alternating-light signal component having a higher frequency than the extraneous light, and for converting the light into a photocurrent (IP), which comprises a useful-signal current (IN) and an extraneous-light current (IF), a coupling unit (3) for decoupling and separating the useful-signal current, which was produced by the optical useful alternating-light signal component, from the extraneous-light current, which was produced by the extraneous light, an amplifying unit (4) for amplifying the useful-signal current, and an energy storage unit (5), which is charged by the extraneous-light current (IF) and which includes a circuit for increasing voltage, wherein the energy stored in the energy storage unit (5) is used to at least partially supply the optical receiver (1) with energy and/or to at least partially supply a measuring arrangement (16) comprising the optical receiver (1) with energy.</p> |
