摘要

高速摄像机正扩展到许多学科的科学实验室。例如,它们可用于监测冲击试验过程,广泛应用于材料的评价。通常,它们在触发脉冲被应用和记录开始之间表现出轻微的延迟。对于许多应用程序,这种延迟可能是至关重要的。本文的作者面临两个问题:需要确定总延迟和需要检查延迟是否随时间变化。因此,设计了本装置。它允许测量相机启动的延迟,范围从1到999毫秒,步长为0.1毫秒。

Testing device design for validation of synchronization between high speed camera and drop weight test machine
High-speed cameras are expanding into science laboratories in many disciplines. For example, they can be used for monitoring of the impact testing course, widely spread in evaluation of materials. Usually, they exhibit a slight delay between the trigger pulse was applied and the recording was started. For many applications, this delay may be critical. The authors of this paper have faced two problems: the need to determine the delay in total and the need to check whether it varies in time or not. Therefore, the hereby described device was designed. It allows measurement of the delay of the camera's start in the range from 1 to 999 ms with the step of 0.1 ms.
