光纤传感在炮口测速中的研究

介绍了光纤传感器的基本原理和炮口测速的测量原理,进行了光纤束排列方式选择的实验和选用不同反射面进行探头与反射面探测距离的实验。根据实验结果绘制了关系曲线并对其进行了详细的分析。通过分析可知,最佳的测试方法是采用共轴内发射分布排列方式的光纤束,探头与反射面的探测距离为1.2mm时反射光强最大。从而为精确测定炮口速度提供了一定的理论基础。

The study of optical fiber sensor on measuring velocity at cannon ostium

The basic theory of the optical fiber sensor and the measuring principle of the pill cannon ostium meterage velocity are introduced.The experimentation on choose the arrange manner of the optical fiber sheaf and choose different reflecting surface to make experimentation on the detecting distance between detect nob and reflecting surface are carried.According to the results of the experimentation,the relation curves are protracted and analyzed particularly.After the analyzing we know,the best testing method is to adopt optical fiber sheaf that the inner launch distributing in common spindle way.When the detecting distance is 1.2mm,the reflecting light intensity between detect nob and reflecting surface reached the biggest.A certainty basic foundation for precision determine the cannon ostium velocity are offered.
