Fourier Ptychography with Scheimpflug Optics for Multi-Aperture Applications [PDF]

open access: yes, 2017
We present a new optical configuration using the Scheimpflug principle for Fourier ptychography microscopy. This configuration minimizes the aberrations present in the off-axis lenses of a multi-aperture Fourier ptychography setup. A 3D printed setup was
