摘要
电火工品的电磁脉冲危害测量采用新型白光光纤温度传感器。测试系统含光纤温度探头、光纤调理器及其测控软件。系统由自带光源发出白光经耦合器进入光纤,传输到探头。探头感受桥丝温度变化并进行光线波长调制。调制光由同一光纤反射回耦合器后,经另一光纤送到光纤解调器,经过A/D转换、信号处理和D/A转换后,以模拟量输出。该信号被高速数据采集卡采集后送入计算机。
A new kind of white light optical fiber temperature sensor is used to test electromagnetic pulse harm to the electric explosive device. The test system consists of optical fiber temperature probe, optical fiber modulator and test-control software. Its own light source gave off white light. The light was transferred to the probe by the optical fiber. The probe took the change of bridge wire temperature, and modulated the ray＇s wavelength. The modulated wire is reflected back to coupler by the right optical fiber, then transferred to optical fiber modulator by another optical fiber, and outputted as analog variable after AID transition, signal processing and D/A transition. The signal was collected by high speed date collection clip and then transferred to computer.
