摘要
Optical communications are made between telescope units that emit diverging signal beacons. Typically the beacon is produced by a diverging, linear polarizing solid state laser and the emission is passed through a spreading lens to a double refracting element (8) that generates a polarization dependent output. This is ed through a transmitting lens (7) to provide the beam.
