A laser strobe tachometer combines a strobe light with a laser speed sensor. The ability of the laser sensor to accurately determine machine speed enables a synchronous strobe rate to be determined without user intervention. Having locked onto the turning speed, the stroboscope can 'freeze' the motion of the shaft, thereby allowing an operator to observe locations, such as on a keyway, flat or screw head, for the optimum placement of the laser spot to generate a once-per-revolution tachometer pulse. 将闪光灯与激光速度传感器相结合的激光频闪测速仪。激光传感器精确确定机器速度的能力使得无需用户干预即可确定同步频闪率。锁定到转动速度之后，频闪观测仪可以"冻结"轴的运动，从而允许操作人员观测最佳放置激光点的位置(如在键槽、平台或螺丝头上)以产生每旋转次的测速脉冲。
