ACCELERATION SENSOR USING FIBER BRAGG GRATING SENSOR AND MANUFACTURING METHOD THEREOF

摘要

Relates to an accelerometer, and a method of producing using a fiber grating sensor, blood once rotatably mounted on the main body, the main body is installed on the object to be measured whole fixture is side by side at one side of the rotating, the the rotating body and that is provided at one side all of the FBG sensor, the time provided in the optical fiber, the optical fiber image that would be installed in a state of maintaining a is bonded to the outer surface of the congestion state of tension of the weight member and the optical fiber for the function of the weight And a tension adjusting unit for adjusting a tension acting on the optical fiber during initial installation. The initial tension of the optical fiber is applied to the optical fiber during the initial installation of the optical fiber to maintain the optical fiber in a tension state. As a result, to avoid measurement errors, and precisely the acceleration of gravity changes due to vibration transmitted from the measured object An effect that can be set is obtained.;
