摘　　要：针对五棱镜各面垂直度误差导致出射光线转角误差的情况,文章提出了一种新的研究五棱镜垂直度与转角误差关系的方法。该方法总结了垂直度误差的影响规律,给出了在棱镜4个面垂直度误差、光线入射角及光线入射方向共6个变量同时影响下的转角误差计算公式,通过仿真计算给出了应用该公式所产生的误差范围。结果表明:转角误差计算公式所计算的结果在合理误差范围内与真值相吻合,可直接应用于相关工程的计算当中。Based on the situation that the steering angle error is caused by the perpendicular error of pentaprism,a new method is proposed to relate the perpendicular error and the steering angle error in the paper.The influence rules of the perpendicular error are summarized and the steering angle error formula with six variables in total are derived.The error range produced in applying the formula has been given by means of simulation and calculation.The results obtained by the steering angle formula are consistent with the truth-value within a reasonable range of error,and can be directly applied in the calculation of related projects.
