Development of vibration measurement system based on distributed configuration with high-speed blanking lights

我们已经开发了一个原型系统，用于测量在两个轴向上的各种机械振动的时间轨迹。它是通过分析高速消光模式的高密度相机图像来实现的。在此研究期间，取得了以下成果：(1)制造了实现消隐光模式的小型LED显示屏；(2)开发了模式位置和方向的检测方法，并检验了检测精度；(3)开发了无需任何特定设备的简化振动评估系统。

We have developed the prototype system for measuring the temporal trajectory of various mechanical vibrations in two axial directions. It is realized by analyzing high-density camera images of high-speed blanking light patterns. In this study period, the following results were obtained:(1) Manufacturing the small LED display for realizing the blanking light patterns,(2) Developing the method for detecting positions and orientations of the pattern, and examining the detection accuracy,(3) Developing the simplified system for evaluating vibrations without any specific equipment.
