1. A method for imaging an object, the method comprising: a. illuminating the object with an illuminating electromagnetic wave via an illumination path, the illuminating electromagnetic wave being characterized by a spectrum of illuminating wavevectors; b. detecting, via a collection path, electromagnetic waves scattered by the object and incident upon a detector, the detected electromagnetic waves being characterized by a spectrum of detected wavevectors; and c. varying the magnitude of at least one of the illuminating wavevectors and detected wavevectors in such a manner as to provide information regarding a scattering characteristic of the object, wherein an aperture, disposed within at least one of the illuminating path and collecting path, has a characterizing dimension equal to or smaller than an instantaneous characterizing wavelength of the illuminating electromagnetic wave.
