Abstract

An offset feedback-type point-ahead method is described and its application to the Engineering Test Satellite VI (ETS-VI) laser communication equipment (LCE) is examined. The role in the method of a high-resolution mirror-deflection mechanism driven by a multilayered piezoelectric actuator is pointed out. The pointing resolution using the method is estimated to be less than 1 microrad at the output of the transmitting optics, which is sufficient of the LCE experiment.
