title: Fiber Bragg grating-based measurement of random-rotation parameters.
abstract: A preloaded rotational sensor featuring a spring packaged within the magnetic head has been proposed and experimentally demonstrated. The aforementioned fiber Bragg grating-based system can convert the strain information into rotation angles without rotation angle limitations in terms of the proposed angle transfer mathematical model. The random-angular displacements were well fitted by the model with the maximum deviation of 0.5°. The linearity of the calculated rotational velocity reaches up to 0.998 in the range of 0 to 2021.4 rpm. This sensor can also be applied in the angular acceleration measurement.
