Abstract

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