| Abstract: | Accompany with the outside pressure changed, the Bragg center reflective wavelength of optical fiber grating changed correspondly. According to the characteristic, a new kind of optical fiber gratting pressure sensor combined with the computer monitor is designed. The measure time of it is 1 ms/point. It can be widely used for train real time tracing. The parameters of train can be given, such as position, velocity, acceleration, disjoint and so on. |
