摘要： A low cost, high reliability system for correcting aberrations in optical signals is disclosed. A foreoptic assembly, such as a telescope, receives an incoming optical signal and directs it to an active optical element, such as a fast steering mirror. The incoming optical signal is diffracted by a diffractive optical element to shape the image that is formed at a wavefront sensor, such as a quad-cell. The wavefront sensor measures a tip-tilt aberration of the incoming optical signal and the active optical element is adjusted to correct the measured aberration. An outgoing optical signal can be transmitted along substantially the same optical path as the incoming optical signal, but in the opposite direction. Thus, the aberration measured from the incoming optical signal can be automatically accounted for in the outgoing optical signal.

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 apparatuses capable of performing appropriate communication according to a distance to a receiving apparatus, optical communication methods, and an optical communication system are provided. A transmitting apparatus transmits an optical signal corresponding to data. The transmitting apparatus modulates intensity of the optical signal into intensity corresponding to a distance over which the data is to be delivered and outputs this intensity-modulated optical signal. This allows the transmitting apparatus to change the intensity of the optical signal corresponding to the data according to a distance to a receiving apparatus that receives the data, which thus allows the receiving apparatus to surely receive the data.

Each node may include an array of pixel elements, each pixel element having an optical detector and an active optical source. The pixel array may be disposed in a backplane of a lens that is configured to map incoming optical signals to pixel locations in the backplane according to their respective angles of incidence and to minimize a deviation at each pixel location between incoming optical signals arriving at the optical detector and emissions from the optical source. The node may include a processor and memory. The processor can register senders in the optical network at locations in the pixel array and can generate routing information by which to route communications from the registered senders to other pixel elements for transmission to their respective destinations.
