transit-time lidar velocimeter

By means of ingenious measurement of correlative signals upstream and downstream,passing time of corresponding peaks of correlative signals is computed and the motion velocity of rolled objects is indirectly meansured.

介绍利用相关技术对运动物体速度进行在线测量的方法和原理,通过巧妙地采集上、下游相关信号,计算出互相关信号峰值对应的渡越时间,间接测量出热轧材运动速度,并在实践中研制出非接触在线相关测速仪。
