Abstract

A new confocal optical method for measuring the dithering amplitude of an aperture near-field optical microscope tip is presented. The methodis direct and absolute, and it provides enough sensitivity to determine movements as small as 5 nm amplitude. Its simplicity provides the opticalnear-field researcher with an in-situ characterization tool for the mechanical properties of the piezo-driver/tuning fork/tip assembly, which is used for the distance control above the sample in most near-field microscopes.
