  • Correcting for aberrations in incoherent imaging systems using fourier ptychographic techniques
    Patent number: 10684458
    Abstract: 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.

  • LASER-BASED FOURIER PTYCHOGRAPHIC IMAGING SYSTEMS AND METHODS
    Publication number: 20190331902
    Abstract: 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.
