Abstract
An optical atmospheric link apparatus transmits information data by means of a light beam, an error signal is generated representative of a difference between a direction of a light beam projected from a optical lens means and a direction of a light beam received from a remote transmitter/receiver and a position of a light path of the light beam incident into an optical lens from a light emission means is controlled on the basis of the error signal so that the direction of the light beam projected from the optical lens becomes coincident with the direction of the light beam received from the remote transmitter/receiver.
