本文主要讨论一种计算曲面全息元件的方法,其特点是利用坐标旋转将曲面全息元件的计算化成平面全息元件的计算。这样处理后,可以使计算简单,物理意义明确。给出了计算实例。
This article focuses on a method of calculating the surface holographic element, which is characterized by the use of coordinate rotation to calculate the surface holographic element into a planar holographic element. This treatment can make the calculation simple and clear physical meaning. A calculation example is given.
