本文根据全息学基本原理,应用光的干涉,衍射理论详细描述了曲面全息元件的成象特性。用位相比较法导出了一套曲面全息光学元件的成象公式及焦距和各项放大倍率计算公式。
According to the basic principle of holography, this paper describes the imaging characteristics of the holographic element in detail based on the theory of light interference and diffraction. The phase contrast method is used to derive the imaging formula, focal length and various magnification formulas of a holographic optical element.
