本文分析了在各种可能的记录和再现条件下平面全息图成像的几何特性,包括像的虚实、倒正、原始像与共轭像的重心、二像的相对位置、象的正视与赝视性等。并纠正了 Lohmann 书中的某些错误,给出了不同条件下像的各种几何特性的示意图,讨论了成像性质与几何参数的关系及某些特例。 This paper analyzes the geometric properties of planar hologram imaging under a variety of possible recording and reproduction conditions, including the true and false images of the image, the center of gravity of the original image and the conjugate image, the relative position of the two images, the frontal and pseudopairy of the image Wait. And some errors in Lohmann’s book are corrected. The sketch of various geometrical characteristics of the image under different conditions is given. The relationship between the imaging properties and geometric parameters and some special cases are discussed.
