摘要:本文针对激光光束指向的精密调整这一技术问题,运用空间矢量分析法,对基于旋转
双光楔的激光光束指向调整原理进行理论计算,给出较为适用的理论基础和原理模型;对所
得原理进行数值仿真和双光楔联动调整技术的原理分析。在此理论基础上,设计了基于双光
楔的激光光束指向精密调整器,并对设计结果进行稳定性、调整范围和分辨力的实验测量。
实验结果表明,所设计的光束精密调整器的光束指向稳定性为每采集十万组数据漂移 ″,
光束空间调整的圆锥区域的张角达到 °、光束指向分辨力满足 1″,调整精度较高,满
足精密调整的范围和要求,适用于精密调整的实验与应用中。

Abstract: In this paper, space vector analysis will be used in the laser beam pointing precision
adjustment of the technical, based on rotating risley prisms to steer the laser beam pointing and to
achieve principle theoretical calculations, give a more theoretical foundation and principles
applicable models; further make numerical simulation and adjustment linkage analysis techniques
principle. Based on this theory, design the precision laser beam manipulator, and test the stability
adjustment range and resolution of the manipulator. Experimental results show that the stability of
the beam pointer vary ″per one hundred thou
