Fourier ptychography for gigapixel imaging

Fourier ptychography (FP) is a recently developed computational technique for high-resolution, high-throughput imaging. This technique stitches together many variably illuminated, low-resolution measurements in the Fourier space to expand the frequency passband and recover the high-resolution complex sample image. Without involving any mechanical scanning, it facilitates gigapixel imaging in a simple, robust, and cost-effective manner. In this talk, I will discuss the applications of the FP approach for gigapixel microscopy, quantitative phase imaging, 3D holographic imaging, spectrum-multiplexing, photographic imaging, and super-resolution fluorescence imaging. The FP innovation may provide new insights for the development of high-resolution, high-throughput imaging platforms using photon, X-ray and electron.
