摘要： A free space point-to-multipoint optical transceiver has a reflective element and an optical feed mounted on the reflective element. When the optical feed is coupled to a light source, the optical feed is positionable to direct light received from the light source onto a reflective surface of the reflective element. Light directed onto the reflective surface is reflected towards a remote location to be received by a receiver located at the remote location. By adjusting a position of the optical feed, the reflected light is aimed. Therefore, adjusting the position of the optical feed provides a technique to track moving remote locations and/or to target different remote locations.

摘要： A free space optical transceiver includes a first holographic optical element (HOE) device having a first recorded interference pattern to diffract a received light signal into a plurality of orders. A second HOE device has a second recorded interference pattern and is positioned relative to the first HOE device to reflect the orders of the diffracted light signal towards corresponding optical components. Use of the reflected orders in this manner in conjunction with the optical components provides the transceiver with multiple functionalities, such as communication, tracking, and alignment. Also, the first and second HOE devices have their interference patterns recorded on an emulsion material that is shaped to provide a common aperture through which to pass a transmitted light signal, thereby adding to the overall compactness of the transceiver.

摘要： A device that controls and reshapes optical signals generated by a laser or sent through fiber optic cables for eventual broadcast to various sectors. The optical train transforms the input Gaussian beam into a flat-top beam, a beam with a uniform intensity distribution. The device can operate either in a super broadband sector spectral output mode, which is a combination of independent orders of diffraction, or be extended to operate as a multi-beam system, where spatially separated beams are obtained at the output of the transmitter. In accordance with aspects of the present invention, both the point-to-sector and multi-beam schemes can be obtained from a single source.
