Abstract

An interferometric technique of a position and beating control for an axial rotating body position is described in this paper. A Michelson interferometer without a signal spectrum transfer in a high-frequency range is used as a position and beating sensor of rotating body. An autocollimator as a reflector insensible to angular rotating is used in a measuring level of the interferometer. The autocollimator is hard connected with a cylindrical information carrier by a magnet lock for motion dynamics investigations. It is found that the position error of the proposed position sensor is no more than (lambda) /8.
