摘　　要：为了研究耐高温胶的固化过程,基于光纤法布里-珀罗腔(F-P腔)传感器原理,将2根光纤的端面作为F-P腔的2个反射腔镜面,用耐高温胶将其封装入氧化锆陶瓷插芯内,制作了一个非本征型光纤F-P腔结构.通过6h谱形监测,发现耐高温胶在自然固化过程中使得F-P腔长变短,表明其在固化过程中收缩,最后趋于稳定,固化引入腔长的变化随时间呈现指数关系,时间常数(下降至1/e)约为40 min.In order to study the curing process of high-temperature resistant adhesives, based on the principle of fiber -optic Fabry-Perot cavity(F-P cavity) sensor, two end faces of optical fibers are used as two mirrors of F-P cavity, which are encapsulated in zirconia ceramic cores with high temperature resistant adhesives, and an intrinsic optical fiber F-P cavity structure is fabricated. Monitoring by 6 h Spectrum, it is found that the length of F-P cavity became shorter during the natural curing process, which indicated that the shrinkage of F-P cavity tended to be stable, and the change of the length of introducing cavity showed an exponential relationship with time, and the time constant (decreased to 1/e) is about 40 min.
