| 摘 要： | 用锥镜产生的无衍射光可以具有大光学口径和光学数值孔径,使无衍射光对入射光束的偏心有一定的包容能力.为了研究无衍射光对激光束角向漂移(角漂)的包容性能,采用发散球面波入射光束,通过理论分析和试验验证可知,发散球面波的无衍射光对激光束角漂具有良好的包容性能.结果表明,此方法产生的无衍射光可适于作中、短距离连续空间直线度误差测量的直线基准.

| Abstract: | Because of the large beam diameter and special characteristics of the non-diffracting beam produced by an axicon,the non-diffracting beam can tolerate the eccentricity of the incident laser beam's axis to the axicon.For studying the additional tolerance property to the incident light beam's deflection,adopting a kind of incident divergent sphere Gaussian wave,it is proved that the divergent sphere Gaussian wave can tolerate the eccentricity of the incident laser beam's axis through theoretical analysis and ... |
