Subresolution imaging: Use of wavelength and angular diversity techniques
Abstract
We calculate the Fourier transform of the electric field at a point on the image of an object as the angle or wavelength of the illumination on the object is varied and show that this function provides a direct measurement of the amplitude and surface height structure of the object within the resolution cell centered at the corresponding point on the object.
