Fraunhofer全息图无透镜再现中的傍轴几何光学理论

Paraxonic geometrical optics in fraunhofer hologramlensless-reconstruction

运用相因子判断法，全面研究了Ｆｒａｕｎｈｏｆｅｒ全息图无透镜再现像的物像共轭关系、放大率关系；在傍轴条件下，针对各种形态的记录方式，分析了记录和再现的各种因素对成像规律的影响，确切完整地给出了傍轴几何光学理论的数学表达和物理解释，并在实验上进行了验证。

By means of phase-factor analysis,the essay has studied in an all-round way the non-image conjugate and the amplification proportional relations in Fraunhofer hologram lensless-reconstructions. And in view of various forms of recording, the essay has also analysed and verified by experiments the influence of all the factors of recording and reconstruction on the imaging laws under the paraxial conditions, and presented a precise and complete mathematical expression and physical explanation for the paraxonic geometrical optics.
