ABSTRACT:
An optical scan type tunnel microscope based on a new principle, having higher resolution, is provided. The apparatus of the invention is comprised of at least an optical fiber 3 whose head portion is covered by an energy acceptor 6, a prism on which a sample which contains an energy donator 7 or is covered by the energy donator 7 is placed, a XY-axis transfer mechanism 9, XY-axis control mechanism 10, Z-axis transfer mechanism 11, Z-axis control mechanism 12, light source 13, optical system 14, and an optical detecting system 15.
