Abstract
A follow-up guidance and information transfer system is disclosed for use between a control point and a moving object utilizing a laser beam generated at the control point. The incident beam is directed by a movable mirror toward the moving object and reflected therefrom by a corner cube or the like along the same path. A detector disposed in the passing zone detects direction and amplitude of deviations of the reflected beam from the path of the incident beam, and a mirror control responds to the detected signals to direct the path of the incident beam to follow the moving object.
