Abstract
A free-space optical lasercom system is disclosed which includes an optical subsystem for receiving an Rx signal and sending a Tx signal, wherein said optical subsystem establishes a focal plane. A first optical fiber with an end coupled to the optical subsystem for directing the Rx signal to an RX detector. A second optical fiber is also included with an end coupled to the optical subsystem for directing the Tx signal from a Tx laser source. A linear X-Y shifting apparatus is used for positioning the respective ends of the first and second optical fibers in the focal plane of the optical subsystem so as to maintain a desired coupling efficiency.
