In this Letter, we propose a method for retrieving the phase of a wavefront from the diffraction patterns recorded when the object is sequentially illuminated by spatially modulated light. For wavefronts having a smooth phase, the retrieval is achieved by using a deterministic method. When the phase has discontinuities, an iterative process is used for the retrieval and enhancement of the spatial resolution. Both the deterministic and iterative phase reconstructions are demonstrated by experiments.
在本信函中，我们提出了一种从物体被空间调制光依次照明时所记录的衍射图样中检索波前相位的方法。对于具有平滑相位的波前，通过使用确定性方法来实现检索。当相位存在不连续性时，则使用迭代过程来进行检索并提高空间分辨率。确定性和迭代相位重建均通过实验得到了验证。
