Summary:Fourier ptychography (FP) is a recently developed computational technique for high-resolution, high-throughput gigapixel 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. I will also discuss our recent developments on a cost-effective whole slide imaging platform, InstantScope.
