OPTICAL RECEIVER FOR RECEIVING LIGHT
The optical receiver has a photodiode (2) for receiving light which has extraneous light and a high frequency alternating light-useful signal part parallel to extraneous light. The photodiode also converts the light in a photocurrent (I-P) which consists of useful signal current (I-N) and an extrane...

| Zusammenfassung: | The optical receiver has a photodiode (2) for receiving light which has extraneous light and a high frequency alternating light-useful signal part parallel to extraneous light. The photodiode also converts the light in a photocurrent (I-P) which consists of useful signal current (I-N) and an extraneous light current (I-F). A coupling unit (3) is provided for decoupling and separating the useful signal current from the extraneous light current. The energy stored in an energy storage unit (5) is used for partial power supply of the optical receiver. Independent claims are also included for the following: (1) an optoelectronic measuring system with an useful signal light source; and (2) a method for storing electrical energy and for receiving optical alternating light-useful signal. |
