19. A reflective-mode Fourier ptychographic imaging system, comprising:

  • a variable illuminator configured to illuminate a sample at a plurality of incidence angles at different times in an epi-illumination mode;

    an optical system comprising a filtering optical element having a filtering function, the optical system configured to receive light reflected from the sample and filter the light reflected from the sample using the filtering optical element, wherein the plurality of incidence angles and the filtering function correspond to overlapping regions in the Fourier domain; and

    a radiation detector configured to acquire a plurality of intensity images, each intensity image corresponding to a different incidence angle of the plurality of incidence angles.
