摘要：

针对金属角锥反射镜的加工装配误差对传输光路的影响，研究了金属角锥反射镜二面角误差与反射光束的关系。详细分析了金属角锥反射镜表面面型及形态对反射特性的影响，并对不同角锥反射镜各个区域的反射率进行测量对比，对金属角锥反射镜的偏振特性也进行分析。研究结果表明，应用于HL-2M 装置CO₂ 色散干涉仪中金属角锥反射镜的表面面形加工精度应在0.3μm 之内，二面角的装调误差宜为正公差且控制在30''内，且表面镀膜的膜层牢固不易脱落。

Abstract:

For the influence of the mental retroreflector processing and installation error on the optical propagation, the relationship between the dihedral angle error of the retroreflector and the reflected beam was studied. The impacts of the surface and morphology of retroreflector on reflection properties was analyzed, and the reflectivity of different retroreflector cone was measured and compared. The polarization characteristics of retroreflector was also analyzed. According to the study results, for the retroreflector in CO₂ dispersion interferometer on HL-2M tokamak, the surface machining accuracy should be within 0.3μm, the dihedral angle error should be a positive tolerance and controlled within 30'', the surface coating is firm and uneasy to fall off.

Key words: Metal retroreflector, Dihedral angle error, Reflection properties, Polarization properties
