The fiber Bragg grating is glued on the surface of an isosceles triangle cantilever beam,which has a step thickness along the beam axis. Due to the electromagnetic force created by a solenoid and a permanent magnet mounted on the top of the beam,a step strain is applied on the fiber Bragg grating. The change of the electric current in the solenoid makes the spectrum of the fiber Bragg grating split. By monitori... Hits: 4522 Download times: 250 View Full Text    Download reader
