The paper describes a novel technique for measuring the velocity of fast flying objects. The technique utilises a series of simple single-use screens which are placed along the expected flight path. The projectile interaction with the screen generates a flash of light which is captured by an optical fibre connected to the light detecting device. The velocities are calculated from the signal arrival times and screen positions. The flash screens were tested using copper shaped charge jets and flyer discs accelerated by explosive charges made of sensitised nitromethane. In addition to the simple time of arrival measurement with VOD-815, the light signals were recorded using an OPTIMEX-64 light analyser which enabled checking their intensity and reproducibility. Some of the experiments were also carried out using a UHSi 12/24 high-speed camera. The flyer plate velocities measured were compared with empirical calculations from a Gurney model.

本文介绍了一种用于测量快速飞行物体速度的新颖技术。该技术利用沿预期飞行路径放置的一系列简单的一次性屏幕。与屏幕的弹丸相互作用产生了闪光，该闪光被连接到光检测设备的光纤捕获。速度是根据信号到达时间和屏幕位置计算得出的。闪屏使用铜制的电荷喷嘴和由敏化的硝基甲烷制成的炸药加速的传单盘进行了测试。除了使用VOD-815进行简单的到达时间测量外，还使用OPTIMEX-64光分析仪记录了光信号，该分析仪能够检查其强度和再现性。还使用UHSi 12/24高速相机进行了一些实验。
