Abstract
Embodiments relate to a local free space optical (FSO) terminal that transmits and receives optical beams. The FSO terminal includes a fore optic, an optical relay system, and an actuator system. The fore optic focuses a receive (Rx) beam to a Rx spot on a focal plane of the fore optic. The focal plane also includes a Tx spot formed by a transmit (Tx) optical beam, however the Rx and Tx spots are laterally separated at the focal plane. The optical relay system creates a conjugate spot for the Rx or Tx spot so that the Rx and Tx fibers may be axially separated. Due to the axial separation, the actuator system can adjust a lateral separation of the Rx and Tx fibers to account for point ahead of the local FSO communication terminal.
