我们提出了一种快速、鲁棒的非干涉波场检索方法，适用于标量相干光束的幅度和相位分布的成像。它基于受控散光下获得的强度测量的多样性，并且可以在标准成像系统中轻松实现。对其在显微镜成像中的应用进行了实验研究。相关实例说明了图像超分辨率、数值重聚焦、定量成像和相位映射的方法能力。
We present a fast and robust non-interferomentric wavefield retrieval approach suitable for imaging of both amplitude and phase distributions of scalar coherent beams. It is based on the diversity of the intensity measurements obtained under controlled astigmatism and it can be easily implemented in standard imaging systems. Its application for imaging in microscopy is experimentally studied. Relevant examples illustrate the approach capabilities for image super-resolution, numerical refocusing, quantitative imaging and phase mapping.
