Joystick Transducer Based on Fiber Bragg Gating
A joy stick transducer based on fiber Bragg grating (FBG) is presented. The sensitivity is analyzed theoretically via discussing the mechanical properties of the elastic element and the strain sensing characteristics of the FBG. By detecting the changing of central wavelength of FBG at different load forces, the response characteristics of the aircraft Joy stick transducer based on fiber Bragg grating are investigated. The experimental results demonstrate that there exists a linear relationship between the central wavelength of FBG and load force, which is consistent with the theoretical analysis. The sensitivities of horizontal and vertical are 2.07 pm·N-1 and 1.80 pm·N-1, respectively, which are consistent with the simulation.
