Abstract

We present a method to measure the actual amplitude of the tip vibration in shear force microscope and near-field scanning optical microscope (NSOM). The method is based on the measurement of the laser light focused on and scattered by the tip. Different from the method already used in NSOM, the equilibrium point of the tip vibration is set to move and both dc and ac part of the scattering light is measured. The dc and ac data can be analyzed to give the actual vibrational amplitude.
