1. A method for performing synthetic aperture optics (SAO) on a target including one or more objects, the method comprising the steps of:

  • illuminating the target with a predetermined number (N) of selective excitation patterns, the N selective excitation patterns determined based on a minimum distance (Δ

    x) between the objects to be resolved by SAO and a width (w) of a detected area captured by a pixel of an optical imaging system for optical imaging of the illuminated target;

    optically imaging the illuminated target at a resolution insufficient to resolve the objects, the illuminated target being imaged by the optical imaging system through a lens included in an imaging path that is physically separated from illumination paths through which the N selective excitation patterns are delivered to the target; and

    processing optical images of the illuminated target using information on the selective excitation patterns to obtain a final image of the illuminated target at a resolution sufficient to resolve the objects.
