A free-space optical data transmission system, comprised of first and second transceivers (10, 10') spaced a distance from each other and having telescop es (14,14') aimed at each other. Each transceiver (10, 10') has a transmitter ( T, T') for transmitting data-encoded light from its telescope (14) to the other telescope (14'), and a receiver (R, R') for receiving light from the other telescope. Each transceiver (10, 10') has a wavefront sensor (WFS, WFS') for determining the curvature of the wavefront of light transmitted between the telescopes, which may be distorted by atmospheric aberrations; and a deformable curvature mirror (DM, DM') connected to the wavefront sensor (WFS,WFS') and in the path of the data-encoded light for modifying the wavefront curvature of the light in response to the wavefront sensor (WFS, WFS'). Preferably, each transceiver (10, 10') has an arrangement for separating the transmitted and received light waves for bidirectional transmission.
