Temperature self-compensated differential optical fibre acceleration sensor probe

The utility model relates to a temperature self-complementing differential fiber acceleration transducing head, which comprise a casing that is a rectangular cube, a cantilever beam that is a triangle and is fixed at the middle position on the inside wall surface of the casing by one side, a mass block that is a spherical body and is fixed at the end part of the cantilever beam away from a fixed edge, and a transmission fiber that is fixedly glued at the reverse root of the cantilever beam by the head end and fixedly glued again definite distance away, wherein, the transmission fiber passes round the mass block at the end part of the cantilever beam and is fixedly glued by two points at the front surface of the cantilever beam, and the other end of the transmission fiber extends out of the casing.
