Abstract
The present disclosure relates to Fourier ptychographic microscopy systems and methods. The system includes: a three-color LED array; a microscope, configured to obtain image information with multi-wavelength, and magnify to generate magnified image information; an RGB camera configured to acquire a first color image with a first resolution based on the magnified image information; and a controller, configured to synchronously control the three-color LED array and the RGB camera, in which the three-color LED array is further configured to display a plurality of illumination patterns, the RGB camera is further configured to acquire synchronously a plurality of first color images, and the controller is further configured to restore a single second image with a second resolution according to the plurality of first color images, and the first resolution is less than the second resolution. The present disclosure improves sampling speed.
