Abstract:
An optical-fiber-acceleration-sensor probe is provided, which includes a probe shell having a threaded hole at a bottom thereof and an optical-fiber entry and exit hole on a side thereof; a double-end stud in the probe shell, an end of the double-end stud being connected to the threaded hole; a high damping elastomer sleeved on the double-end stud; a mass block sleeved on the double-end stud and located on the high damping elastomer; an optical fiber interferometer located in the mass block and including a sensing arm and a reference arm, where the sensing arm is wound around the high damping elastomer, and the reference arm is wound around the mass block; high damping vibration absorbers on the mass block; and a nut located at another end of the double-end stud, and on the high damping vibration absorbers, where a washer is between the nut and the high damping vibration absorbers.
