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.
最近，我们提出了一种使用孔径阵列滤波器的非迭代相位恢复方法的相干衍射成像。本文首次（据我们所知）展示了这种相干成像的实验演示，其中通过相位恢复方法，从通过方形孔径阵列滤波器传输的物体波场的离散衍射强度中，重建出由二极管激光照明的复值物体。这种成像方法只需要单次测量衍射强度，并且不需要迭代相位恢复算法中使用的物体支撑约束紧密或全息技术中使用的参考波。
