摘要
在双谱线原子发射光谱测温原理的基础上,设计了对炸药爆轰的瞬态温度进行实时测量的光纤光谱测试系统,利用光学纤维将炸药爆轰的光谱信号传入测光系统,用多通道数据采集器处理数据,系统的时间分辨率可高达0.1μs,所选择的两条谱线的波长分别为CuI 510.5和CuI 521.8nm,为炸药爆温的测量提供了一种简单有效的方法。利用该测温系统,通过对炸药爆轰光谱的测量,获得了实时瞬态爆轰温度-时间分布曲线。
Based on the principle of double lines of atomic emission spectroscopy, a measurement system of transient optic fiber spectroscopy to determine the detonation temperature of explosives has been designed. In this method, the spectral signal of explosives detonation is transferred into the measurement system with a telescope and optical fiber, and collected by multichannel transient record. Its time resolution can reach as high as 0.1 mus. The wavelengths of the two spectral lines are Cu 1 510.5 and Cu 1 521.8 run, respectively. This temperature measurement system is simple and effective for detonation temperature measurement. Through the measurement of detonation spectral signal of the explosive, the transient detonation temperature-time distribution plots were obtained using this temperature measurement system.
