| 摘 要： | 基于频域方法实现了数字记录和再现三维物体离轴全息图.通过频谱对应关系求得各个面的频谱分布,使用数字滤波方法,成功地消除了零级衍射和共轭像;通过改变再现距离,分别获取了三维物体各个截面的再现像.

| Abstract: | A method for numerically recording and reconstructing off-line hologram of a 3-dimension object is described.Based on the relationship of spectra,the spectrum band in each plane can be calculated.By using digital filter method,conjugate images and zero-order diffraction images are eliminated.And the layers of the 3-dimension object are reconstructed through using different distances between reconstructed image and CGH. |
