    摘要: Eine optische Empfangseinheit umfasst eine Detektoreinheit zum Erfassen optischer Strahlung, eine elektronische Steuer- und Auswertungseinheit, die mit der Detektoreinheit in Verbindung steht und dazu ausgebildet ist, basierend auf der von der Detektoreinheit erfassten Strahlung ein Empfangssignal zu erzeugen, und eine Sammeloptik, die eine Eintrittsfläche definiert und dazu ausgebildet ist, auf die Eintrittsfläche auftreffende optische Strahlung in Richtung der Detektoreinheit zu fokussieren. Die Detektoreinheit umfasst zwei separate Strahlungssensoren. Die Eintrittsfläche der Sammeloptik weist zwei separate Zonen auf, wobei jede der separaten Zonen dazu ausgebildet ist, die auf sie auftreffende optische Strahlung lediglich in Richtung eines der separaten Strahlungssensoren zu fokussieren.

    摘要: A free-space laser communication system for bidirectional transmission of telemetry data in Gigabit Ethernet (GBE) protocol using a dual atmospheric effect mitigation approach. This free-space bidirectional GBE laser communication system utilizes an Optical Combining Receiver Array and a Framer/Forward Error Correction/Interleaver (FFI) device to mitigate the combined effects of atmospheric turbulence and channel fading. Since the FFI device is designed for Synchronous Optical Network (SONET) protocol, an intelligent (or smart) media converter is used to convert GBE telemetry data to SONET frames, which enables the FFI device to perform an error correction algorithm and provide a seamless error-free GBE laser communication link for distance over a kilometer. This bidirectional laser communication system can be implemented with low-cost commercially available components.

    摘要: Optical communication systems and methods using coherently combined optical beams are disclosed. A representative system includes a first data source for sending first data at a first frequency of a first optical beam to a first aperture, and at a second frequency of a second optical beam to a second aperture. The system further includes a second data source for sending second data at a third frequency of a third optical beam to the first aperture, and at a fourth frequency of a fourth optical beam to the second aperture. The system also includes a first interleaver of the first aperture configured to interleave the first data at the first frequency and the second data at the third frequency; and a second interleaver of the second aperture configured to interleave the first data at the second frequency and the second data at fourth frequency.

    摘要: A network node, network controller node and methods for supporting communication with user equipment within a wireless telecommunication network are discussed. The network node comprises: an antenna for receiving and transmitting wireless telecommunication communication signals to a user equipment, said wireless telecommunication signals being within a first frequency band. A receiver for receiving an electromagnetic signal transmitted wirelessly from a network controller node within said wireless telecommunication network, said electromagnetic signal being within a second frequency band, said second frequency band being a different frequency band to said first frequency band, said receiver comprising a retro-reflector for reflecting said electromagnetic signal back towards said network controller node. The network node further comprising a modulator operable to modulate at least one property of said electromagnetic signal in dependence upon said signal received from said user equipment such that information received from user equipment is conveyed via modulations in said reflected electromagnetic signal to said network controller node.

    摘要: Techniques are disclosed that can be implemented as a light-based communications network exhibiting gossip network topology. In some embodiments, the network may include a plurality of mobile and/or fixed communicating nodes (peers) configured for light-based communications with one another. To that end, a node may host a transmitter (e.g., laser, LED, or other solid-state light source) configured to emit light-based communication signals and/or a receiver (e.g., a photosensor or other light-based data input device) configured to sense such signals. In some instances, the gossip topology may provide for relay and aggregation of information from node to node, improving reliability and availability of information propagated within the network. In some embodiments, the network may be autonomous (e.g., self-forming and/or self-serving).
