Abstract: A pointing unit (100) for use with a free space optical (FSO) communications terminal (105). The pointing unit (100) includes an optical arrangement of a first (101) and second (102) pair of rotatable steering elements (101a, 101b, 102a, 102b). The steering elements are controlled according to a control scheme (10) to steer a beam (107b) towards a target (110).

Abstract: A pointing unit (100) for use with a free space optical (FSO) communications terminal (105) including an optical arrangement (101) of one or more optically transmissive steering elements (101a, 101b). The steering elements (101a, 101b) are arranged in an optical path of an incident beam (107) entering the optical arrangement (100), and the orientation of at least one element (101a, 101b), and the refractive index of at least one element (101a, 101b), are controllable to steer a beam (107b) towards a target (110).

Abstract: A free space optical receiver including a multi-mode transmission medium configured to receive a light beam comprising a plurality of modes, the light beam having been propagated through a free space path. The free space optical receiver also includes a mode separating means configured to separate the plurality of modes for transmission through a corresponding first plurality of transmission media as a corresponding plurality of single-mode light beams, and a combining means configured to combine two or more of the plurality of single-mode beams into a combined beam for transmission through a further transmission medium.
