【摘要】 X射线成象技术是弹道研究的有效手段,采用X射线数字化成象技术可以提高实验效率。弹道研究的对象是一个几毫秒的瞬态过程,并且为减少高速运动对象的运动模糊,X射线源的脉冲宽度仅为20ns。而采集一幅图象需40ms。这些因素制约着X射线数字化实时成象技术在弹道研究领域的应用。本实验室采用硬件延迟控制触发和软件循环采集保存的手段,实现了瞬态过程的X射线数字化实时成象功能。本文介绍硬件设计与软件设计的原理。更多还原

【Abstract】 The X-ray imaging technique is a valid means in study of trajectory, and the X-ray digital imaging technique can increase to experiment the efficiency. It is a several millisecond transient process in trajectory study, and decrease the object sport mistily of the high speed exercising, the X-ray pulse width is only for 20 ns. But the image scan period need 40 ms. The X-ray digital imaging technique is restricted the realm’s application in the trajectory study by these factors. We used the means of the hardware delay control trigger and the software circularly saving, realized the flash process X-ray digital imaging function. This paper introduces the design principle of the hardware and the software.更多还原
