论文摘要
在这里，我们介绍了三维单枪ptychography（3DSSP）。 3DSSP利用单次几何形状独有的另一个约束来解除3D对象的多个2D平面。数字模拟和分析计算表明，3DSSP在扩展的3D对象中重建多个平面，最小间隔与常规显微镜的景深一致。我们通过重建轴向分离5 mm的正交头发链来实验证明3DSSP。三维单光ptychography为超快时间尺度上动态发展的系统的体积成像提供了途径。
Here we introduce three-dimensional single-shot ptychography (3DSSP). 3DSSP leverages an additional constraint unique to the single-shot geometry to deconvolve multiple 2D planes of a 3D object. Numeric simulations and analytic calculations demonstrate that 3DSSP reconstructs multiple planes in an extended 3D object with a minimum separation consistent with the depth of field for a conventional microscope. We experimentally demonstrate 3DSSP by reconstructing orthogonal hair strands axially separated by 5 mm. Three-dimensional single-shot ptychography provides a pathway towards volumetric imaging of dynamically evolving systems on ultrafast timescales.
