In contrast, a self-driving car's LIDAR system, which stands for Light Detection and Ranging, uses a narrow invisible infrared laser.

相比之下，自动驾驶汽车的激光雷达系统，代表光探测和测距，使用一种窄的不可见的红外激光器。

The researchers used a mapping method called Light Detection and Ranging, or LiDAR.

研究人员使用了一种称为光探测和测距或 LiDAR 的测绘方法。

He asked if I had heard of this new technology called LiDAR -- Light Detection And Ranging.

他问我是否听说过这种叫做激光雷达的新技术——光探测和测距。

" The inside looks like a crystal cave because the limestone has leaked calcite into little stalactites, " says Lin, who entered the tomb and used lidar (light detection and ranging) to explore it on the show.

“里面看起来就像一个水晶洞，因为石灰岩中的方解石已经渗漏成了小钟乳石，”他进入墓室，并在节目中使用激光雷达（光探测和测距）进行了探索。
