Abstract

Aiming at the deviation of the actual light emission direction of the periscope terminal system from the theoretical light emission direction, the optical axis pointing model of the periscope laser communication terminal was established based on the multi-body system theory, and the influence of the mechanical axis system error and the optical axis system error on the pointing model was analyzed, and through the analysis of the sensitivity of the pointing error factors, the error with the greatest influence on the final apparent axis error was obtained as the elevation 45° plane mirror slope angle error. Followed by the slope angle error and wedge angle error of the azimuthal 45° plane mirror, which provides a basis for the correction of pointing errors.
