Computational illumination for high-speed in vitro Fourier ptychographic microscopy [PDF]

, 2015
We demonstrate a new computational illumination technique that achieves large space-bandwidth-time product, for quantitative phase imaging of unstained live samples in vitro. Microscope lenses can have either large field of view (FOV) or high resolution,

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

, 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

Microcamera aperture scale in monocentric gigapixel cameras [PDF]

Applied Optics, 2011
Multiscale cameras achieve wide-angle, high-resolution imaging by combining coarse image formation by a simplified wide-field objective with localized aberration correction in an array of narrow field microcameras. Microcamera aperture size is a critical parameter in multiscale design; a larger aperture has greater capacity to correct aberration but ...
