      SensitivityResonant frequencyAdvantages of this design sensor
      Proposed sensor43 pm/g460 HzOne fiber has two fiber gratings,and a new circular cycloidal hinge structure and a partially elliptical mass block structure are used
      Ref.[7134.8 pm/g800 HzThe sensor also has two gratings for a single optical fiber,but the sensor height reaches 50 mm,and the height of the sensor is 24 mm
      Ref.[11132.53 pm/g780 HzThe sensor places two gratings on different optical fibers,requiring two optical fiber interfaces for data acquisition
      Ref.[1220 pm/g1 300 HzThe sensor has a high resonance frequency,and it has also etched two gratings on the same optical fiber,but the sensor is less sensitive
      Ref.[101.94 nm/g91 HzAlthough the sensor has high sensitivity,the resonance frequency of 91 Hz is too low to meet the actual needs
