Paper Abstract

A dynamic acceleration measurement system based on a high sensitivity compliant cylinder fiber optic probe and an all-fiber configuration Distributed Bragg Reflector (DBR) fiber laser with self-mixing technique is presented. The compliant cylinder fiber optic probe consists of a mass-block and an elastic cylinder twined with single mode fiber and can be regarded as being close to that of a simple mass spring system. Experimental results show that the signal to noise ratio (SNR) can achieve 50dB at 800 Hz under 1.5 mg acceleration stimulation, voltage sensitivity is 6.04 V/g and minimum detectable acceleration of the measuring system is 4.7μg/sqrt Hz at 800Hz. Moreover, the material of elastic cylinder is polyurethane (PU) which has better temperature stability and can be applied widely in the field of vibration measurements.
