Rotational speed sensors based on a fiber Bragg grating
Opto-Electronics and Communications Conference-OECC(2017)
摘要
A novel rotational speed sensor consisting of a fiber Bragg grating is proposed. As the grating glued to the surface of a metal rod was driven by a disc, the grating wavelength was shifted back and forth to cause the change of reflection power for measuring the frequency of on-off change for obtaining the rotational speed.
