Amplifying technique for light pulse

光脉冲放大技术

The length of time the lidar’s light pulse takes to return to the satellite provides information about where the clouds or particles are in the atmosphere.

激光雷达的光脉冲返回卫星所消耗的时间提供了大气中云或者粒子的位置信息。

Analogous to a snow avalanche on a steep mountain slope, an incoming light pulse initially frees just a few charge carriers which in turn free others until the original signal is amplified many times.

像陡峭山坡上的雪崩一样，一束入射光的脉冲最初仅仅释放少数的电荷载子（charge carrier），这些电荷载子再轮流释放其他的载子，直到原始信号被放大很多次。
