Fourier ptychography is an advanced imaging technique that combines principles of both Fourier imaging and phase retrieval to achieve high-resolution images with improved contrast and depth of field. This technique involves capturing a series of low-resolution images of an object under different illumination conditions and then computationally combining them to reconstruct a high-resolution image. Fourier ptychography has applications in microscopy, remote sensing, and other fields where high-resolution imaging is critical. It has the potential to revolutionize imaging technologies by enabling detailed imaging of samples that were previously difficult to visualize.
