摘要： Disclosed is an atomic force microscope. A Fabry-Perot interferometer where the intensity of light reflected at a cantilever through an optical fiber varies sensitively to a displacement of the cantilever is constructed to accurately measure a distance between the optical fiber and the cantilever. A Fabry-Perot resonator is formed by the optical fiber having an end of a concave mirror shape and a reflective surface of the cantilever. A displacement of a cantilever tip is measured by detecting a signal reflected at the resonator and a feedback signal corresponding to a variation in the displacement of the cantilever tip is generated. The displacement of the cantilever tip is kept constant by actuating a piezoelectric element in a Z-axis direction.
