Effect of dispersion of linear birefringence upon the sensitivity of an optical current sensor

Theoretical analysis of the temperature characteristics of an optical current sensing element

“…Reference [12] Verdet Constant Temperature (unit:K) trace reported the effect of the variation of stress-induced linear birefringence with temperature upon the output scale factor. According to the results of reference [12], together with the expression of residual linear birefringence in reference [13], the temperature characteristic of the linear birefringence in each sensing arm is shown in Fig. 4.…”

“…The effects of the peak wavelength shift of the optical source with temperature upon the output scale factor due to the dispersions of the linear birefringence, the reflection-induced-retardance and the Verdet constant of the sensing element were reported in references [13][14][15], respectively. Experiment showed that as temperature changes from 283 K to 303 K, the peak wavelength of the optical source changed from 1292 to 1302 nm.…”
