Abstract:The fiber Bragg grating(FBG)sensor with strong anti-interference ability and quasi-distributed sensing is taken as the research object. Aiming at the demodulation technology that is crucial to its application,two aspects of high-precision demodulation of static signals and real-time high-speed demodulation of high-frequency signals are presented.The existing demodulation technologies are classified from two dimensions of measurement field and software and hardware design,which can better help relevant personnel to choose a demodulation technology that matches the tested object better. |
