This article gives an overview of the many fields in which these methods can be useful. Beam shaping includes the use of carefully designed … WebbThe wavefronts of a wave originating from a point source are spherical.

Webb波前（英文名：wavefront），有时也被称为波面。 其实个人会觉得叫波面更贴切，因为它描述的就是一个和光线传输方向垂直的一个曲面，也就是 光束中各等相位点所形成的面，与光束各点的传播方向垂直。 举几个最容易理解的例子，如果是理想平行光，那么他的波前就是一个平面；换成一个点光源的话，对应的波前就变成一个球面（类似于电场线和等势 …
