Abstract

A real-time vibration measurement and analysis system based on fiber optic sensor and high-speed DSP processor is introduced. Measurement is emphasized in recent engineering field for checking the bearable capability of objects on vibration. Real-time processing ability, testing accuracy and dynamic testing range are crucial aspects in a measurement and analysis system. Using fiber optic displacement sensor to capture the dynamic measurements during a vibration test is presented. FFT recursion algorithms based on split-radix and twiddle vector is proposed for achieving fast speed frequency analysis of vibration signals. Experiment results show the superiority of the proposed approach compared to the one based on single-chip processor. High speed and real-time testing power is achieved in this system.
