Abstract

Optical current sensor has a wide range of applications. The main factors that affect the practical process of optical current transducer (OCT) are the effects of birefringence, temperature and long-term stability. Optical current transducer (OCT) with thin slice type sensing head is designed in this paper. Due to the small size of the sensing element of sensing head, the influence of the transient birefringence caused by temperature gradient is negligible. The long-term operation stability of the system is improved by using the non bonding package; the measurement sensitivity of the system is improved by using a new type of magneto-optical material BiGd: YIG. The experimental system used LD as light source, PIN as photoelectric detector, and PC to acquire output signal and data process. The experimental results show that the output signal is linear with the magnetic field in the range of 1909.19Oe, and the feasibility of this design is verified.
