Abstract

A pointing control system has been designed based on a CCD array and a fine steering mirror. The control system accurately points a transmit laser ahead of an incoming beacon laser without requiring accurate prestabilization of the beacon line of sight. The digital design of the control loop and a laboratory demonstration of CCD-based laser pointing are presented.
