最近，我们提出了一种基于孔径阵列滤光片的非迭代位相恢复相干衍射成像方法。本文给出了这种相干成像的第一个(据我们所知)实验演示，其中被半导体激光器照射的复值物体是由物体的波场的孤立的衍射强度重建的，该物体通过一个方形孔径的阵列滤光片，使用相位恢复方法。这种成像方法只需要一次衍射强度的测量，并且不需要迭代相位恢复算法中使用的紧密物体的支撑约束，也不需要全息技术中使用的参考波。
Recently, we have proposed a coherent diffractive imaging using a noniterative phase retrieval method with the filter of an aperture array. The first (to our knowledge) experimental demonstration of this coherent imaging is presented here, in which a complex-valued object illuminated by a diode laser is reconstructed from the isolated diffraction intensities of the object's wave field, transmitted through an array filter of square apertures by using the phase retrieval method. This imaging method requires only a single measurement of the diffraction intensity and does not need a tight object's support constraint utilized in iterative phase retrieval algorithms or a reference wave used in holographic techniques.
