说明：  Fourier Ptychography是一种首先开发用于显微镜的成像技术。该技术首先收集感兴趣的显微样品的一系列图像。从相干光源（通常从LED阵列）以不同的照明角度获取每个图像。然后，使用迭代相位检索算法将获取的图像集组合为最终的高分辨率图像，该图像可以包含多达十亿个像素（千兆像素）。该技术还提供了非干涉相位图像和近波长衍射极限分辨率。(Fourier Ptychography is an imaging technique first developed for use in microscopes. The technique first collects a series of images of a microscopic sample of interest. Each image is acquired under a different angle of illumination from a coherent light source (typically from an array of LEDs). The acquired image set is then combined using an iterative phase retrieval algorithm into a final high-resolution image that can contain up to a billion pixels (a gigapixel). The technique also provides a non-interferometric phase image and near wavelength diffraction-limited resolution.)
