In this paper,the characteristics of and the problem with polarization pulsed magnetic field photonic sensors in practice are presented,together with a theoretical analysis on the effects of scaling factors on the sensitivity of optic sensors.The theoretical expression for scaling factors is derived through the improvement of the conventional algorithm,and in addition,a new method for improving the characteristics of magnetic field photonic sensors is proposed.The results show that the experimental data of scaling factors agree well with the theoretical analysis.
