The shift of reflective wavelength of one FBG under external strain is translated into a change in time interval of the optical pulse from another FBG drived by a PZT plate.
The effects of wavelength range and sampling interval selected on the results have been discussed. The results obtained were in good agreement with those by Kalman filter method.
