我们演示了同时从一个单一的散焦图像的均匀对象的相位和振幅提取。在推导中明确说明的假设下，该算法解决了同轴全息的孪生图像问题，并且能够分析使用X射线显微镜、电子显微镜、中子显微镜或可见光显微镜获得的数据，特别是当它们涉及散焦和点投影方法时。我们的简单，强大的，非迭代和计算效率的方法被施加到使用X射线相衬超显微镜获得的数据。
We demonstrate simultaneous phase and amplitude extraction from a single defocused image of a homogeneous object. Subject to the assumptions explicitly stated in the derivation, the algorithm solves the twin-image problem of in-line holography and is capable of analysing data obtained using X-ray microscopy, electron microscopy, neutron microscopy or visible-light microscopy, especially as they relate to defocus and point projection methods. Our simple, robust, non-iterative and computationally efficient method is applied to data obtained using an X-ray phase contrast ultramicroscope.
