论文摘要
检测光学透明样品之间的相位变化通常是一项艰巨的任务。我们提出并展示了一个紧凑，轻巧和低成本定量相比成像仪。从针孔衍射的光被入射在厚的物体上，并通过图像传感器收集调制光，并记录强度模式。比较了两种光学配置，即基于镜头和无透镜的情况。实现了修改的回相算法，以从单个相机拍摄的不同轴向平面从不同的轴向平面提取样品的相位信息。
Detection of phase variations across optically transparent samples is often a difficult task. We propose and demonstrate a compact, lightweight and low cost quantitative phase contrast imager. Light diffracted from a pinhole is incident on a thick object and the modulated light is collected by an image sensor and the intensity pattern is recorded. Two optical configurations namely lens-based and lensless cases are compared. A modified phase-retrieval algorithm is implemented to extract the phase information of the sample at different axial planes from a single camera shot.
