SHSD Demodulator of Interferometric Integrated Optical Acceserometer Based on SOPC

Abstract:

It is described that the acceleration signal is modulated to optical phase by Micheson interference device and demodulated by Synthetic-heterodyne signal demodulation(SHSD) ,when the error is compensated by alternating current phase tracking homodyne compensation scheme (PTAC). Then the digital signal proseccing system is designed with SOPC technology. And DSP and intelligent data communication interface run in parallel . The experiment has shown that when the virtual value of external acceleration signal is constant, in selected working frequency range, the system output signal can trace the vibration acceleration signal linearly and reliably.
