Embedded pupil function recovery for Fourier ptychographic microscopy: erratum.
In the original paper, the line width of the resolution target (which corresponds to half-pitch resolution) was used to characterize the resolution of our microscope system. However, we think that full-pitch resolution offers a better definition of the imaging system's resolution limit. In this erratum, we list specific sections from the manuscript that used half-pitch resolution and correct th...
متن کاملEmbedded pupil function recovery for Fourier ptychographic microscopy.
We develop and test a pupil function determination algorithm, termed embedded pupil function recovery (EPRY), which can be incorporated into the Fourier ptychographic microscopy (FPM) algorithm and recover both the Fourier spectrum of sample and the pupil function of imaging system simultaneously. This EPRY-FPM algorithm eliminates the requirement of the previous FPM algorithm for a priori know...
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...
متن کاملQuantitative phase imaging via Fourier ptychographic microscopy.
Fourier ptychographic microscopy (FPM) is a recently developed imaging modality that uses angularly varying illumination to extend a system's performance beyond the limit defined by its optical components. The FPM technique applies a novel phase-retrieval procedure to achieve resolution enhancement and complex image recovery. In this Letter, we compare FPM data to theoretical prediction and pha...
