1. A method for operating a computational microscope, the method comprising
capturing images of a sample by a camera array of the computational microscope under multiple illumination patterns provided by the computational microscope, wherein the camera array comprises multiple groups of camera units,
wherein each group of camera units comprises two or more camera units each configured to capture images with a different polarization,
wherein each camera unit of the camera array is configured to capture images of an area of a sample,
wherein the multiple illumination patterns are generated from an illumination source comprises multiple groups of light source units,
wherein each group of light source units comprises two or more light source units configured to generate different polarized lights to the sample,
wherein the multiple illumination patterns comprises two or more single polarization illumination patterns with each single polarization illumination pattern generated by light source units generating a same polarized light;
forming multiple sets of images from the captured images,
wherein each set of images is formed from the captured images captured by camera units of the camera array having a same polarization and under a single polarization illumination pattern.
