We adopted Gaussian beam, ray tracing and vector diffraction integration together to analyze single beam spot-focusing lens antenna.

本文采用将高斯波束法，射线追迹和矢量衍射积分相结合的方法来分析单波束的点聚焦透镜天线。

It is shown that the ray trajectory depends strongly on the spot size and the inclination of the incident beam and the structure of the lens.

计算结果表明，光线轨迹主要由入射光束的光斑尺寸、倾角和透镜的结构决定。

The radius and position of waist spot of CO2 laser beam focused by a single Ge lens were measured experimentally, and the focal length of the Ge lens was determined. The result is in agreement w...

实验测量了经单一锗透镜聚焦后的CO_2激光束的腰斑半径和位置，同时确定了聚焦锗透镜的焦距，其结果与实际情况一致。
