摘要
The invention relates to an optical reception device (16) for receiving a signal from an antenna array (12) comprising: - a light source (62) generating an optical carrier and M phased optical beams which are frequency-shifted relative to the optical carrier; - a collection circuit (64) comprising N paths (74) connected to an antenna (18), and comprising a modulator (78) of an incident signal; a beam-forming network (66) connecting (M+1) first ports (86) to N second ports (88) connected to one path (74), M first ports (90) being connected to the optical beams and a control port (92) connected to the other ports (86, 88) so that a maximum optical intensity on the control port (92) corresponds to phased signals on the N second ports (88).
