Patent ID: 8731414

Claim:
Optical receiver for receiving alternating-light data signals and for storing electrical energy obtained from extraneous light, comprising a photodiode for receiving light, which comprises the extraneous light and an alternating-light data signal component having a higher frequency in comparison to the extraneous light, and for converting the light into a photocurrent (IP), which comprises a data signal current (IN) and an extraneous light current (IF), wherein the extraneous light excludes optical data transmission light sources and optical energy transmission light sources, a coupling unit for decoupling and separating the data signal current (IN), which was generated by the optical alternating-light data signal component, from the extraneous light current (IF), which was generated by the extraneous light, an amplifying unit for amplifying the data signal current (IN) and an energy storage unit, which is charged by the extraneous light current (IF) and which comprises a circuit for increasing voltage, wherein the energy stored in the energy storage unit is used for at least partially supplying the energy for the optical receiver and/or for at least partially supplying the energy for a measurement arrangement comprising the optical receiver.
