My study on neutron optics started in 1970 when I got the information of the neutron mirrors and the neutron guide tube in the Technical University of Munich. I, however, had limited my neutron optics on the neutron mirrors and the neutron guide tubes until 1985. Since 1990, I have challenged to the neutron spin interferometry together with my collaborators, which include new young physicists too.
