However, such a divergent beam can be transformed into a collimatedbeam by means of a lens.
然而,这种散射的光束可以通过镜头的帮助被转化成平行光束。
2
The theoretical expressions of the collimatedbeam of a DHCL are derived by transmission theory, and the numerical results are also given.
基于光线传输理论导出该结构柱透镜准直激光光束的基本公式并给出数值模拟的结果。
3
If a monocentric system existed for which an incident collimatedbeam emerged as exactly collimated, then the system would give geometrically perfect imaging of any point in space.
