Two instruments were involved in producing the map: the camera instrument (specifically the Wide Angle camera) and the Lunar Orbiter Laser Altimeter (Lola) instrument.
制作这份地图利用到两种仪器：相机设备(特别是广角相机)和月球轨道激光测高仪(萝拉)。
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。
