Abstract : A newfiber sensor for measuring surface roughness using ratio of diffuse and reflections is introduced. It expatiates the structure , working principle and characteristic of the fiber sensor , and the practically measuring result is given. The fiber sensor has strong ability of anti2jamming , high survey precision , good replication quality , and can measure exiguity surface and bottom surface of the hole. The factor which affecting the measurement are analyzed and discussed.
