    Schematic of DHM with structured illumination.
    Fig. 1. Schematic of DHM with structured illumination.
    Resolution enhancement of DHM by the structured illumination. (a) Spectrum evolvement of the object wave during the imaging process. (b) Flowchart of the iteration process for resolution enhancement. The black dots denote high frequency components of the object; the red-dashed circles denote the NA of the optical system.
