CALIBRATION OF FIBER OPTIC ACCELEROMETERS BY SHAKER BASED VIBRATION TEST SYSTEM

• Abstract:

  A unique type of fiber optic accelerometer based on wavelength modulation by the Bragg grating principle has been developed.
  Testing, characterization and calibration of such transducers represent a challenge since they are not readily compatible with conventional data acquisition platforms.
  To overcome this technical challenge a system based on a precision vibration exciter driven by a newly released vibration controller has been configured.
  With this system the optical transducer system can be tested and the frequency response determined.
  This shaker based vibration test system represents a very useful solution for testing any new accelerometer technology that is not directly compatible with conventional data acquisition platforms.
