Abstract:
1. A method for imaging an object, the method comprising: a. illuminating the object with a substantially coherent beam of electromagnetic radiation, the coherent beam characterized by a wavelength; b. interposing a diffracting medium in the near field of the object, the diffracting medium for diffracting said electromagnetic radiation illuminating the object including scattering evanescent waves in the near field, the diffracting medium characterized by a structure of scale length varying with position; c. transferring the electromagnetic radiation diffracted by said diffracting medium to form a convolution image at least partially from the evanescent waves scattered with the diffracting medium substantially at a focal plane; d. detecting the convolution image; and e. deconvolving the convolution image with respect to the structure of the diffracting medium for obtaining an image of the object.
