Abstract
Near-field scanning optical microscopy and Fourier analysis polarimetry are combined to obtain quantitative maps of the local retardance, (resulting from strain or crystalline birefringence), fast axis orientation, diattenuation and diattenuating axis orientation in nanostructured polymer thin films. Lateral resolution of 50 nm with retardance sensitivity as small as 1 mrad has been demonstrated in images of isotactic PS crystallites and diblock copolymer morphologies.
