摘要
本文应用平面几何及光学原理,从理论和实践上分析了应用激光多普勒测速仪(LDV)进行实际测量时,在有窗口的情况下应该注意的几个问题,并给出了测量点位置偏差修正的定量公式以及光轴方向上测速精度相对误差的评估方程,省略了繁琐的理论推导.
By using geometric and optical principles,the measuring window of LDV has been discussed.The quantitative correction formula for themeasuring error in the posi- tion of inspection points and the method for the evaluation of relative errors on velocity measuring accuracy are given.
