The influence of the circular
birefringence on the measurement performance was analyzed based on the
Polarization Properties of FBG in this paper. Due to the circular
birefringence, the linear relationship between the max of PDL and pressure has been broken down. To estimate the cross
sensitivity, a new parameter named relative
