摘要
使用复波前矩阵Q^(-1)、Q复光线矢量概念和广义ABCD定律,对像散光束在自由空间的传输特性进行了研究,揭示了有像散特性的激光束在各向同性自由空间中的传输规律,并以数值计算例对所得结果作了说明。
The propagation of astigmatic beams in free space is studied in detail by using complex wavefront matrices Q-1,Q, the concept of complex ray vector and the generalized ABCD law. The characteristics of astigmatic Laser beams propagating in homogeneous free space are discussed, and numerical calculations are performed to illustrate the results.
