Abstract
A knock mode scanning near-field optical microscope comprises a light source member, an optical fiber probe connected at one end thereof with the light source member such that other end of the optical fiber probe forms a near-field point source of light, and that the optical fiber probe is attached with one end of a suspension arm member of an oscillation member. The oscillation member further has a piezoelectric ceramics, which is disposed on the suspension arm member, and is driven by a harmonic wave signal by a signal feedback member so as to bring about a change in amplitude and phase of the optical fiber probe in order to result in a feedback control.
