摘要： A wireless optical transceiver system which includes a passive optical antenna coupled by optical fiber to an active electronics module. The transceiver system receives and transmits light beams from/to the atmosphere, and thereby communicates optically with a second optical transceiver. Receivers, transmitters, repeaters, switches, routers, etc., may be similarly organized, i.e. by coupling one or more passive optical antennas and an active electronics module with fiber-optic cable. Furthermore, various network topologies and organizations may be arranged using one or more of the fiber-coupled transceivers, receivers, transmitters, repeaters, switches, routers, etc. Such components are admirably suited for use in various network configurations such as broadcast networks, point-to-multipoint networks, etc. due to their low cost, ease of installation and antenna sighting, modularity, and upgradability. An optical router for establishing wireless channels to a number of subscribers may be configured based on demodulation and remodulation of light beams, or alternatively by redirecting light beams by adjustable deflection mirrors. A communications network infrastructure based on atmospheric light beam propagation is contemplated.

摘要： A laser communication system for full duplex wideband data transmission includes first and second terminals having dichroic wavelength-multiplexed optical systems wherein transmitted and received light are multiplexed along a path through the same aperture. The optical systems each preferably comprise a cassegrain receiver having primary and secondary mirrors (200, 70) for directing both transmitted and received laser light. Modulated laser light is generated by a high-power laser diode which is actively cooled by a thermoelectric cooler (34). A window (191) in the housing (94), through which the modulated laser light travels, includes a transparent resistive coating to which electrical current is applied to control the temperature of the window (191). The aspheric primary mirror has a highly reflective surface, preferably a single-point diamond turned mirror surface, formed on an aluminum substrate as a single piece.

摘要： A system and method for positioning and aligning a node within a network includes a position determination device configured to determine the position of the node, and a digital compass to determine the orientation of the node within the network. Position and pointing information obtained from these devices can be used to compute a pointing angle of one or more transceivers in the network node to establish communication links. The digital compass can also provide roll and pitch information to facilitate leveling of the node, or to allow pointing systems within the node to compensate for leveling inaccuracies. Additional communication channels can be provided.

摘要： A system and method for networked high-speed data communication through free space is described. The system includes one or more central networks, which contain one or more lasers modulated with high-speed data to illuminate with laser light areas surrounding the central network in which are located one or more user networks. The laser from the central network generates a radiation pattern that is sectored into horizontal and vertical sectors, and further divided into channels for each wavelength. Data coming from the user networks modulates a laser, which is transmitted as a collimated beam through free space back to the central network where it is received. Communication can be point-to-point, point-to-multipoint, multipoint-to-point, or multipoint-to-multipoint, and the point-to-multipoint communication can be broadcast, simulcast, or multicast.
