Popis:	A new method concerning secure free-space communications by means of chirped laser pulse interference is proposed. Physical-layer security of the link is ensured by encoding the data in a relative phase difference between two spatially separated beams. The possible architecture of the dual-node link is discussed based on acousto-optic elements for signal modulation and detection.
