摘要： A system for measuring torque to which a body is subjected by twisting the body about an axis defined thereby. The system includes one or more fiber Bragg gratings secured to the body. Each of the fiber Bragg gratings is positioned so that the fiber Bragg grating is located at least partially non-parallel with the axis of the body. The system also includes one or more light sources for providing light transmittable to the fiber Bragg grating(s). The light transmitted to the fiber Bragg grating(s) is filtered thereby to provide a modified light having one or more characteristic spectra. The sys tem also includes an analyzer for analyzing said at least one characteristic spectrum to determine the torque to which the body is subjected.
