The hardware design of optical fiber strain sensor demodulation system

A new type data acquisition and real-time processing system of linear array CCD high-speed is introduced in the paper, which includes the high-speed ADC, high-speed cache FIFO, comparator module, digital signal processor (DSP) module and display module. The comparator module starts Data storage and reading, which make DSP processing only the effective pixels and reduce the computational burden. That increases the running speed so that the system can achieve real-time processing. The system can carry out real-time display and communicate with the host computer.
