论文摘要
PtyChography是一种广泛用于显微镜的技术,用于实现高分辨率成像。这种方法依赖于从样本的几个部分照明产生的衍射模式中收集的图像的计算处理。在这项工作中,我们研究了使用不同形状来阐明上述样品的效果:凸形形状,例如圆形和常规多边形,以及类似于QR代码的未连接形状。我们的结果表明,使用无连接的形状似乎在收敛性方面优于凸形形状,在某些情况下是准确性的。
Ptychography is a technique widely used in microscopy for achieving high-resolution imaging. This method relies on computational processing of images gathered from diffraction patterns produced by several partial illuminations of a sample. In this work, we numerically studied the effect of using different shapes for illuminating the aforementioned sample: convex shapes, such as circles and regular polygons, and unconnected shapes that resemble a QR code. Our results suggest that the use of unconnected shapes seems to outperform convex shapes in terms of convergence and, in some cases, accuracy.
