中文摘要：
圆锥棱镜的锥角小于5°的情况下可被视作一个失调系统，运用该失调系统的4×4阶增广矩阵和失调系统的衍射积分公式分析了高斯光束通过圆锥棱镜的传输特性，得到了出射光场的解析表达式，给出了出射光束在z轴上光强的变化规律。研究了将圆锥棱镜和透镜组合来实现实心到空心、实心到局域空心转换以及转换条件。
英文摘要：
The axicon was regarded as a misaligned system at the condition of the cone angle 〈 5° and the 4 × 4 augmented matrix of the misaligned system has been gotten. Propagation properties of Gaussian beams through an axicon have been studied by using the misaligned diffraction integral. The expression and the region of the hollow and solid of the output beam also have been studied. The transformation condition of the beam from solid to hollow or from hollow to solid has beam realized through combining the axicon and the lens has been investigated.
