Numerical comparison between shear force constant height and constant intensity images in scanning near-field optical microscopy

摘要

Abstract: We present a numerical comparison between shear-force, constant-height and constant-intensity images in scanning near-field optical microscopy. We demonstrate the general difference between the three images. Two type of incident light are tested of polarization in perpendicular and parallel direction with respect to the mean plane of the surface. Merits and demerits of the three images are discussed.!19
