摘要
对半凹旋转棱镜对光束的变换进行了详细的理论分析，定量计算了变换光束的空间强度分布。结果表明经半凹旋转棱镜变换产生的光束具有近似“无衍射”性质。
Starting from the imaging properties,the imaging transformation properties of the semi concave axicon is theoretically analyzed.Also the intensity distribution of the output beam is numerically calculated.The calculation has proved that the beam transformation through a semi concave axicon has the characteristics called “approximate diffraction free beam”.
