光纤,由于它重量轻、保密性好、电磁隔离度好、无接地回路和不受电磁干扰,以及没有像暴露在脉冲核辐射下电导体中所产生的电流脉冲,因而对军事应用具有吸引力。人们曾认为某些纤维光波导应是耐核辐射影响的,但是,我们已经发现,很多被认为耐辐射的光纤,实际上甚至对中等剂量的辐射都是非常敏感的。辐射对纤维光波导具有两种主要的光效 Fiber optics are attractive for military applications due to its light weight, good confidentiality, good electromagnetic isolation, ungrounded circuits and immunity to electromagnetic interference, as well as the absence of current pulses in electrical conductors as exposed to pulsed nuclear radiation . It has been considered that some fiber optic waveguides should be resistant to nuclear radiation, however, we have found that many fibers considered radiation-resistant are in fact very sensitive to moderate doses of radiation. Radiation has two main optical effects on fiber optical waveguides
