Wide-field, high-resolution Fourier ptychographic microscopy
In this article, we report an imaging method, termed Fourier ptychographic microscopy (FPM), which iteratively stitches together a number of variably illuminated, low-resolution intensity images in Fourier space to produce a wide-field, high-resolution complex sample image. By adopting a wavefront correction strategy, the FPM method can also correct for aberrations and digitally extend a micros...
متن کاملWide-field Fourier ptychographic microscopy using laser illumination source.
Fourier ptychographic (FP) microscopy is a coherent imaging method that can synthesize an image with a higher bandwidth using multiple low-bandwidth images captured at different spatial frequency regions. The method's demand for multiple images drives the need for a brighter illumination scheme and a high-frame-rate camera for a faster acquisition. We report the use of a guided laser beam as an...
متن کاملAperture scanning Fourier ptychographic microscopy.
Fourier ptychographic microscopy (FPM) is implemented through aperture scanning by an LCOS spatial light modulator at the back focal plane of the objective lens. This FPM configuration enables the capturing of the complex scattered field for a 3D sample both in the transmissive mode and the reflective mode. We further show that by combining with the compressive sensing theory, the reconstructed...

متن کاملModeling Extensions of Fourier Ptychographic Microscopy
Fourier ptychographic microscopy (FPM) is a recently introduced procedure that acquires highresolution (0.37 2 μm 2 ), wide field of view (120 mm 2 ) giga-pixel optical images [1]. Its operation closely parallels the principles supporting conventional ptychography, the well-known X-ray and electron imaging procedure. Instead of combining a sequence of diffraction images captured from a sample a...
