The lunar Orbiter laser Altimeter (LOLA) works by sending a laser pulse through an optical lense that splits it into five beams that are each scattered back after they strike the lunar surface.
月球探测器上的激光高度计(LOLA)的工作原理为：发射一束激光脉冲，利用光学镜片将其分为五道光线，当光线到达月球表面后会自动反射至激光高度计上。
Micro-computer control system controls the sending of pulse series and realises the change of speed, amplitude and frequency in vibratory tapping.
微型计算机控制系统控制脉冲序列的发送，实现振动攻丝中转速、振幅和频率的无级调整。
