چکیده
Full optical fiber current sensor phase modulation is the use of magnetic field made the refraction different of left-handed and right-handed circularly polarized light, and the linearly polarized light can be decomposed into a left-handed and right-handed circularly polarized light. The paper proposes research and design of reflective optical fiber current sensor based on improved phase modulation. This paper analyzes the current sensor reflective polarization of light changes, and using the Jones matrix analysis method to establish a reflective fiber optic current sensor model. Design of reflection type optical fiber current sensor model can improve the sensitivity of optical fiber current sensor. Copyright © 2013 IFSA.
