We propose and numerically explore a method that upgrades a conventional single-shot microscope into a single-shot ptychographic microscope, without impairing its optical performance. It is based on splitting the microscope’s intermediate image plane into multiple replicas, and detecting a set of their coded Fourier transform magnitudes, using a different sensor for each replica. To code each beam, it is transmitted through a distinct coding mask. A ptychographic phase-retrieval algorithm is used to reconstruct the imaged object’s complex-valued transmission function. The proposed method also enables ultrahigh-speed imaging by using a pulse-burst as illumination and applying a multi-state reconstruction algorithm. This approach paves the way to both single-frame and ultrahigh-speed, diffraction-limited microscopy of complex-valued objects.

高分辨率（受衍射限制）单次多路复用编码孔径笔录

我们提出并在数值上探索了一种在不损害其光学性能的情况下将传统的单次显微镜升级为单次柱状图显微镜的方法。它基于将显微镜的中间图像平面分成多个副本，并使用每个副本的不同传感器来检测其编码傅里叶变换幅度的集合。为了对每个光束进行编码，它通过不同的编码掩码传输。刻印术相位检索算法用于重建成像对象的复数值传递函数。所提出的方法还可以通过使用脉冲猝发作为照明并应用多状态重建算法来实现超高速成像。这种方法为复数值对象的单帧和超高速，衍射受限的显微镜学铺平了道路。
