| 摘 要： | 针对高速运动喷雾图像的实时采集技术，开发出用于柴油机喷雾测试的实时图像采集系统。对喷雾初始信号的探测、脉冲激光器触发以及图像采集之间的时序关系进行了研究，并通过试验测得了ＣＣＤ摄像机对光强的响应特性。最后，给出了该系统在柴油机喷雾开始后延时０．９ｍｓ实时采集的喷雾图像实例。

| Abstract: | The technique of grabbing fuel spray image moving at high speed in real time was studied,and the measurement system of diesel spray was developed. The time serial of the spray initial signal,ruby laser and digital image system was analyzed. The responding characteristics of CCD video camera to light intensity was investigated experimentally. At the end of this paper,the grabbing fuel spray image delayed 0. 9ms was showed. |
