论文摘要
当前的幽灵成像阶段重建方案需要复杂的光学系统,傅立叶变换步骤或迭代算法,这可能会增加系统设计的难度,从而导致相位检索错误或花费太多时间。为了解决这个问题,我们提出了一种五步相移的方法,其中不需要复杂的光学系统,傅立叶变换步骤或迭代算法。有了五个设计的不连贯的来源,一个人可以获得五个不同的相应的幽灵成像模式,然后可以从这五个斑点模式中计算对象的相位信息。通过具有两种复杂对象的数值模拟来证明该理论建议的适用性,结果说明了复杂对象的相位信息可以成功地和定量地重建。
The current ghost imaging phase reconstruction schemes require either complex optical systems, Fourier transform steps, or iterative algorithms, which may increase the difficulty of system design, cause phase retrieval error or take too much time. To address this problem, we propose a five-step phase-shifting method in which no complex optical systems, Fourier transform steps, or iterative algorithms are needed. With five designed incoherent sources, one can obtain five different corresponding ghost imaging patterns, then the phase information of the object can be calculated from those five speckle patterns. The applicability of this theoretical proposal is demonstrated via numerical simulations with two kinds of complicated objects, and the results illustrate the phase information of the complicated object can be reconstructed successfully and quantitatively.
