An imaging method and system are presented for use in sub-wavelength super resolution imaging of a subject. The imaging system comprises a spatial coding unit configured for collecting light coming from the scanned subject and being spaced from the subject a distance smaller than a wavelength range of said light; a light detection unit located upstream of the spatial coding unit with respect to light propagation from the object, and configured to define a pixel array and a spatial decoding unit, which is associated with said pixel array and is configured for applying spatial decoding to a magnified image of the scanned subject, thereby producing nanometric spatial resolution of the image.
