“…In order to solve the problem that high resolution and large field of view cannot be combined in the microscopic system, Zheng et al [1] combined with phase retrieval [2][3][4][5] , the concepts of ptychographic imaging [6][7][8][9] and synthetic aperture [10][11][12] proposed Fourier ptychographic microscopy (FPM). The technique requires the use of LED arrays to achieve frequency domain scanning [13][14][15][16][17] , so many researchers have made in-depth studies on how to improve the LED model.…”

Fourier ptychographic microscopy technique combines the concept of phase retrieval algorithm and synthetic aperture, which can solve the problem that large field of view and high resolution cannot coexist. However, describing the linear transfer process of the imaging system by coherent transfer function in conventional calculations leads to ringing artifacts. Gaussian apodization coherent transfer function constraints is proposed and embedded into the software platform, and a high-resolution Fourier ptychographic microscopy imaging system is constructed together with the designed hardware. The proposed algorithm can reduce the ringing artifacts and ensure the accuracy and resolution of the reconstructed results by simulating experiments and acquiring real images.
