Fourier Ptychography is a technique that is different from conventional microscopy used to construct a high-resolution image from several low-resolution images of the same scene. In this method, LED arrays replace the light source of a conventional microscope. LEDs are turned on in succession to take low-resolution images. As the position of the LED changes then the Fourier Transform of the image shifts. This method is better than conventional microscopy as there is moving parts and hence the results do not suffer from position accuracy. It helps to get an aberration-free large field of view of an image. In this paper, the imaging procedures in Fourier Ptychography are studied and the forward imaging model, recovery process, aberration correction, and sampling requirements are also discussed.
