点源全息中的几何方法和衍射方法

Geometric and diffractional method in holography of piont objects

讨论了点源全息中的两种研究方法，第一种是几何方法，可以用光线的符号，但不能给出任何有关系统分辨率的信息；第二种方法是衍射方法，在线性近似下。

Two methods for holography of point objects are investigated. The first method is a geometric method. It permits us to use the notion of a light ray but does not give any information about the resolution of the system. The second method is a diffractional method. It gives full information about the properties of the system in the case of linear approximation.
