Abstract: An optical system includes an optical antenna configured to receive and/or transmit laser beams through a first aperture, a gimbal-mounted deformable mirror (GDM) configurable to correct aberrations of a received laser beam, a power selector configurable to split the received laser beam into a first light beam and a second light beam, a wavefront sensor configured to measure a wavefront of the first light beam, a collimator configured to couple the second light beam into an optical fiber, and a controller configured to control the GDM for laser beam tracking and for correcting the aberrations of the received laser beam based on the wavefront of the first light beam measured by the wavefront sensor. The GDM is configurable to scan, within a field of regard (FOR), a beacon beam to be transmitted for laser beam tracking; or scan within the FOR to acquire a beacon beam transmitted by a terminal.

Abstract: Aspects of the present disclosure relate to adaptive coding of digital communications, such as for a free-space optical channel. Some implementations can transmit, via a first transceiver over a communications channel, a first series of data packets to a second transceiver. The first transceiver can receive a second series of data packets from the second transceiver, and an adaptive coder can analyze the second series of data packets to detect transmission conditions of the communications channel. The adaptive coder can execute one or more proactive actions based on the detected transmission conditions, such as sending error correction information for the first series of data packets and/or modifying one or more future transmission characteristics, and can do so before information regarding the reception of the first series of data packets is received from the second transceiver.
