However, such a divergent beam can be transformed into a collimated beam 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。
The theoretical expressions of the collimated beam 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。
If a monocentric system existed for which an incident collimated beam emerged as exactly collimated, then the system would give geometrically perfect imaging of any point in space.
当入射光束与出射光束平行时，单色同心光学系统空间任一点成几何理想像。
The optical system includes at least one lens element, which outputs the light in a collimated beam on the oscillating reflector regardless of an orientation of the oscillating reflector.
该光学系统包括至少一个透镜元件，其与振荡反射器的定向无关地以准直光束的形式将光输出在振荡反射器上。
