“…Finally, all low-resolution images are combined with a phase retrieval algorithm to recover high-resolution images. In recent years, this method has provided a new idea for quantitative phase measurement [7], optical aberration correction [19,20], and high-resolution imaging [21]. It has been widely used in quantitative phase microscopy imaging [18], high-speed in vitro live cell imaging [22], super-resolution fluorescence microscopy [23], and other fields.…”

How to perform imaging beyond the diffraction limit has always been an essential subject for the research of optical systems. One effective way to achieve this purpose is Fourier ptychography, which has been widely used in microscopic imaging. However, microscopic imaging measurement technology cannot be directly extended to imaging macro objects at long distances. In this paper, a reconstruction algorithm is proposed to solve the need for oversampling low-resolution images, and it is successfully applied to macroscopic imaging. Compared with the traditional FP technology, the proposed sub-sampling method can significantly reduce the number of iterations in reconstruction. Experiments prove that the proposed method can reconstruct low-resolution images captured by the camera and achieve high-resolution imaging of long-range macroscopic objects.
