Abstract :

Conventional imaging systems demonstrate a clear trade-off between resolution and field-of-view in acquired images. This review discusses a new method called Fourier Ptychography (FP), which leverages super-resolution to overcome this trade-off in image generation. Specifically, FP sequentially captures low-resolution images under different illumination angles and stitches them in the frequency domain. The variety of angles enables access to multiple frequency regions. This method can be implemented on simple microscopes with an exchange of optical design complexity for computational complexity to achieve high-quality imaging. This paper demonstrates how to use FP in a fast, robust, and low-cost manner. An experimental model using an embedded system, namely Raspberry Pi 4, a low-cost microscope, is proposed to achieve super-resolution enhancement and wide-field imaging with sub-micron resolution. This microscopy can be assembled using a collection of readily available parts.
