摘要
在菲涅耳衍射区和夫琅禾费衍射区,分别利用输入面上的多个随机二元纯相位调制,获得多个输出面强度信息,在不需要输入面强度先验信息的基础上,基于迭代算法高精度重构了复杂光场的波前。讨论了菲涅耳衍射区和夫琅禾费衍射区各自特点和适用范围。
Abstract
Without prior intensity information in input plane,one method using random binary phase modulation and iterative algorithm is adopted to reconstruct complex wave-front in Fresnel and Fraunhofer diffraction domains,respectively. Three or more diffraction patterns in Fresnel or Fraunhofer domains with different random binary phase masks are used to successfully retrieve the complex wave-front. The differences of the methods used in Fresnel or Fraunhofer diffraction domains are finally discussed in detail.
