光学电流传感器由其良好的安全性和抗干扰性能等优点引起了广泛关注,已逐步成为替代传统电磁式电流互感器的先进电流传感设备.在全光纤电流传感器的研究中,光学材料的费尔德常数是非常重要的物理参数,与全光纤电流传感器的测量灵敏度密切相关.然而,基于法拉第磁光效应的光学电流传感器目前在测量稳定性与可靠性方面受到很大的限制,这主要归因于这种传感器技术存在较大的线性双折射等因素影响.同时,基于相同原理的传统费尔德常数测量方法也面临了这些因素的影响而导致测量不准确.本文首先基于折射率光频色散原理,建立了采用分光光度法测量光学材料费尔德常数的新方法,采用石英与PMMA材料和光纤研究新方法和传统方法对费尔德常数测量的影响.对提高全光纤电流传感器测量灵敏度,拓展其应用领域具有指导意义.
