Abstract: Introduction was made to the principle of Faraday effect, circular birefringence and Marius theorem based on full optical fiber current sensor. The mathematical model of the system was built by using Jones matrix. The full optical fiber current sensor was simulated through Optisystem optical software, modulating for right-handed circularly polarized light with sinusoidal phase. The results show that the output of light intensity figure can correspond with the modulation signal waveform. It is verified that the mathematical model and system simulation are reasonable, which can effectively provide the reference for future real sensor design and manufacture.
Key words: full optical fiber; current sensor; Faraday effect; circular birefringence; light intensity
