摘要
在聚焦、扩束、准直等需要改变光能量分布的场合 ,考证了高斯光束特征参数b、W0 在传输变换中对选择物距、透镜焦距及光学系统的指导作用 ,考证了虚像存在的条件 ,并分析了b、W0
This paper discusses the lens focal length and optical system for the case of light energy distribution variation, such as focusing, expanding, collimating of light beam, etc, the role of the characteristic parameters of Gauss beam in choosing object distance, and also analyzes the effects of b and W 0 on the results of beam transformation.
