The reproduction study of 3D Computer-Generated Fresnel Hologram

摘要

A Computer-Generated of three-dimensional Hologram reproduction method is presented based on the theory of optical holography. In this paper, a mathematical model of three-dimensional objects is established. The Fresnel wave information of object is sampled according to the sampling theorem after simulated by computer. The object Fresnel wave amplitude is obtained by the Fresnel diffraction formula so that the Hologram can be calculated by FFT. Consequently, the object image can be acquired using each pixel value of image reproduction. And we use Euclidean distance to calculate the similarity of reproduced image and the original image so that the experimental results appear more intuitive. The proposed algorithm in this paper is not complex and time saving and suited to practical engineering application. So the technique can be infiltrated into medicine, archeology, military, aviation and other fields.
