REMOVAL TYPE OPTICAL FIBER SENSOR AND MEASURING METHOD USING THE SAME

摘要

PURPOSE: A removable optical fiber sensor and a measurement method thereof are provided to improve the reliability of measured data by directly measuring excavation area. CONSTITUTION: A removable optical fiber sensor comprises a main body(100) and an optical fiber(200). A through-hole is formed at the core part of the main body and an optical fiber mounting part is formed at the side of the main body in the longitudinal direction. The optical fiber is drawn out from the rear end of the main body to the front end of the main body through the through-hole. The main body is laid under the ground. An optical fiber protecting part is mounted on the outer surface of the optical fiber. The optical fiber protecting part is mounted on the optical fiber mounting part.
