Tensorial tomographic fourier ptychography

A Fourier ptychography system, comprising:

• a polarization-sensitive camera positioned for capturing a sequence of polarized images of a sample;
• an objective lens positioned in a light path between the polarization-sensitive camera and the sample;
• an array of light sources for directing light to the sample;
• a generator polarizer positioned between the array of light sources and the sample to polarize light directed to the sample from the array of light sources;
• and
• a computing system coupled to the polarization-sensitive camera and configured to create a tomographic Fourier ptychography image by:
• receiving, from the polarization-sensitive camera, the sequence of polarized images of the sample in the light path that passes through the generator polarizer, the sample, and the objective lens, wherein each polarized image of the sequence of polarized images overlaps another polarized image of the sequence of polarized images;
• stitching each image of the sequence of images together using a non-linear Fourier transform function to create a composite image;
• and
• outputting the composite image as the tomographic Fourier ptychography image.
