Abstract

A tracking control loop was designed for precision beam pointing based on a high frame rate CCD array and a fine steering mirror. The effect of CCD frame rate and readout delay on performance of control loop was analyzed. A digital compensation filter was designed to achieve high bandwidth tracking with a CCD frame rate of 2 KHz.
