The need for extremely precise positioning of pre-objective galvonometer based laser pointing systems necessitates calibration to correct for various system distortions. Such distortion errors fall into two categories: those inherent to the geometry of the scanning system layout, including galvonometer mounting configuration and lens specification; and those related to the behavior of the galvonometer as a precise positioning mechanism. This paper examines system error sources in pre-objective scanning systems and proposes several techniques to correct them.
