Abstract: A free space optical communications terminal (100) including an optical arrangement of a quarter-wave plate (105), a Faraday rotator (110), a polarisation splitter (115), a first arm (120) comprising a receiver (126) and a transmitter (128), and a second arm (130) comprising a component (132) configured to utilise a received beam. The optical arrangement apportions a circularly polarised beam between the first and second arm.

Abstract: A pointing unit (100) for use with a free space optical (FSO) communications terminal (105) that includes 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).
