摘    要：通过分析光束漂移对光电测距瞄准误差的影响,作者认为,只要测距仪光发射系统存在空间相位分布不均匀,测距的瞄准误差就是不可避免的.减小这种误差的根本方法是限制空间相位分布不均匀度,其次是选择大气湍流弱的时间进行观测.

Abstract: Having analyzed the influences of light-beam shifting on ranging pointing error, authors consider that so long as there exists spatial phase distributing nonuniformity of light transmission system of ranger exist, ranging point error is inevitable. To reduce this error, the spatial phase distributing nonuniformity must be strictly limited, and ranging must be carried out when atmospheric turbulence is weak.
