摘要
对透明物场的菲涅尔数字全息成像技术进行实验研究;完成全息物场的记录,使用菲涅尔数值算法和角谱再现算法分别从空域和频域再现了全息物场,对再现像采用数字图像处理的方法消除了零级衍射像,改善再现像的像质,并对菲涅尔数字全息术的成像特性进行讨论.
The operation for recording of Fresnel digital holography is experimentally presented and reconstructed image is obtained by Fresnel transform algorithm and angular spectrum algorithm.The approach of digital image processing is applied to improve the reconstructed image.And imaging character of Fresnel digital holography is discussed detailedly.
