Not Accessible

Your library or personal account may give you access

Abstract

In this paper, a non-equilibrium optical fiber Michelson interferometer is used to realize non-contact micro vibration measurement. The frequency response range of 10~300Hz and the displacement resolution of 2nm in vibration are realized.
