Abstract

See full text

A method of obtaining two orthogonally polarized super-resolution images is provided. A first diffraction-limited image is obtained using horizontally polarized light; a second diffraction-limited image is obtained using vertically polarized light; and, the first and second images are processed so as to yield a convoluted image having super diffraction-limited performance in both dimensions. Enhanced alignment of CAD image to acquired image is facilitated using the horizontally and vertically polarized images.
