数字全息中再现像分离问题的研究
Separation of the Reconstructed Images in Digital Holography
【摘要】 详细分析了数字全息的再现像分离条件 ,指出数字全息和普通全息的再现像分离条件之间的区别 ,同时也讨论了再现条件对数字全息记录光路的要求 ,同时给出一种能部分避免再现像重叠的处理方法 ,并做出相应的实验验证
【Abstract】 The separation of the reconstructed images in digital holography is analyzed firstly.Then the difference between the reconstructing condition of the digital holography and that of the classical holography is pointed out. At last, the geometrical arrangement of the optical components is studied, and a spacial frequency filtering method is introduced to partly avoid the overlapping. Some verified experimental results are given.
