CORRELATION BETWEEN OPTICAL AND TOPOGRAPHICAL IMAGES FROM AN EXTERNAL REFLECTION NEAR-FIELD MICROSCOPE WITH SHEAR FORCE FEEDBACK

摘要

An external reflection scanning near-field optical microscope with shear force regulation of the tip-surface distance is described. Near-field optical and shear force topographical images are compared for various samples. It is shown that the most important correlative relationships between these images can be deduced from symmetry considerations. The possibility of extracting additional information from the optical images is demonstrated on images of human blood cells. [References: 11]
