Abstract
An automatic alignment mechanism for use in a reciprocal tracking laser communicator. A cylindrical transceiver unit having oppositely disposed laser transmitter and detector sections is mounted within an outer cylinder. The outer cylinder has an open end and a closed end with a spherical, mirrored inner surface. Means for mounting the cylindrical transceiver positions the detector facing the mirrored inner surface and constrains the detector to movement in the focal sphere of the mirror. Electromechanical means, responsive to received optical energy reflected by the mirror and focussed onto the detector, rotates the transceiver in accordance with the location of the blur circle of said energy on said detector so that the transceiver is aligned with the source of the optical transmission.
