| 摘 要： | 为解决检测面尺寸较大时CCD难以得到高质量数字全息图的问题,本文利用负透镜设计光学系统让CCD接收来自物体的缩小虚像,以球面波为参考波,使用单色CCD近距离得到三种色光照射下的大尺寸彩色物体的数字全息图,然后采用可控放大率波面重建算法得到同一尺寸的数字全息重建像,合成彩色数字全息重建像.同时,使用两种消零级方法去除零级...

| Abstract: | In order to improve the quality of digital hologram of large size object,a method of recording large size object with a short distance is presented.With spherical wave as reference wave,the digital hologram of large size color object image,which is illuminated with differently wavelengths(red,green,blue),is recorded by using of optic system with negative lens.Then each monochromatic holographic image is reconstructed with the same magnification,and the corresponding digital color holographic image is acquir... |
