摘　　要：光纤温度传感器因其在测量和传递信号部分没有电磁的参与,完全不受电磁的干扰。它的抗电磁干扰(EMI/RFI)特性使其具有传统温度传感器无法比拟的应用优势。光纤温度传感器测温是最新的温度测量技术,在强电磁环境下正在取代传统的电介质测温方式。在医疗、核电、工业测温领域有着广阔的发展前景。本文将此新型温度传感器应用于医用磁共振成像系统的永磁体温度控制,详细介绍其工作原理、系统实现并指出其应用优势。Fiber optic technology provides intrinsic immunity to EMI and RFI. Fiber optic sensors are not electronically active and do not emit nor are they affected by any type of EMI and RF radiation. This kind of EMI/RFI characteristic can not comparable than any traditional temperature sensor. Fiber optic temperature sensor is the brand new temperature measurement technology, it will be a substitute of the traditional temperature measurement method in the field of strong magnetism. It must be the great application on the medical, nuclear power and industry temperature measurement field. This article will explain the brand new fiber optic temperature sensor applies to medical MRI system, it covers principle and application advantages.
