By use of a micro - displacement set we realized a very high precision tuning . the experimental results verified the theoretical predication . the realized tuning ranges of the two ofbg are 6 . 320nm and 5 . 762nm respectively 同时,建立了ofbg调谐测试装置,实现了ofbg的高精度线性调谐,两根光栅分别实现调谐范围6 . 320nm和5 . 762nm ,调谐装置具有很好的重复性。
At the same time we based on the high precision tuning mechanism and computer controlling feed - back technology to design pid controller . so , we finished design of closed - circuit controlling system and achieved the goal of sampling and feedback 同时,本文在高精度的调谐机构的基础上,利用计算机控制反馈技术,设计了速度式pid控制器,完成了闭环反馈控制系统的设计,实现了输出参量光信号采集和反馈的目的。
