STRUCTURE OF FBG SENSOR FIXING ON ONE BODY MATERIAL WHICH CAN MEASURE THE DEFORMATION DEGREE OF THE FIXING MEMBER

摘要

PURPOSE: A structure of FBG sensor fixing on one body material which can measure the deformation degree of the fixing member is provided to simplify a structure by preventing thermal deformation and breaking of optical fiber.;CONSTITUTION: A structure of FBG sensor fixing on one body material comprises a fixing member(10) and a optical fiber grating sensor(9). The fixing member is formed in a fixing unit(20) and made of a member which physically moves as same as a measurement target. The fixing member is fixed in order to change according to the external physical power. The fixing unit is formed inside the sensor-device(S). The optical fiber grating sensor is integrally formed with the fixing member.;COPYRIGHT KIPO 2012
