Certain embodiments pertain to techniques for coded-aperture-based correction of sample-induced and system-induced aberration.

Systems and methods for coded-aperture-based correction of aberration obtained from Fourier ptychography

Aberration-corrected incoherent imaging methods and systems that can acquire a sequence of coherent images and an incoherent image of a specimen, implement an embedded pupil function recovery process in junction with Fourier ptychographic technique to construct an improved resolution image and pupil function of the imaging system using the sequence of coherent images, determine an optical transfer function based on the estimated pupil function, and remove the aberration from the incoherent image using a deconvolution process to generate an aberration-corrected incoherent image.

Correcting for aberrations in incoherent imaging systems using fourier ptychographic techniques

Certain embodiments pertain to pupil ptychography methods and systems.

Pupil ptychography methods and systems

Certain aspects pertain to Fourier ptychographic imaging systems, devices, and methods that implement an embedded pupil function recovery.

Embedded pupil function recovery for fourier ptychographic imaging devices

Certain embodiments pertain to laser-based Fourier ptychographic (LFP) imaging systems, angle direction devices used in the LFP imaging systems, optical switches used in the LFP imaging systems, and LFP imaging methods. The LFP systems include an angle direction device for directing laser light to a sample plane at a plurality of illumination angles at different sample times. The LFP systems also include an optical system and a light detector. The optical system receives light issuing from the sample being imaged and propagates and focuses the light to the light detector acquiring raw intensity images.

Laser-based Fourier ptychographic imaging systems and methods

Certain embodiments pertain to Fourier ptychographic retinal imaging methods and systems that focus on a retina of an eye to acquire a sequence of raw retinal images, construct a full-resolution, complex retinal image from the sequence of raw retinal image and correct the aberration in the full-resolution, complex retinal image to generate a substantially aberration-free retinal image.
