分析了变视场下探测器对Beer-Lambert定律的多次散射修正。我们引入了将接收到的辐射功率与两种不同实验情况下的参考功率水平相关联的传输函数。在第一种情况下，传输函数将接收功率与适合于非衰减介质的参考功率电平相关联。在第二种情况下，通过使接收器到达相对于源的近距离位置来建立参考功率电平。为了考察探测器视场变化的影响，研究了增益因子的行为。给出了激光在雾、云和雨中传输的数值模拟结果。
The multiple scattering corrections to the Beer-Lambert law in the case of a detector with a variable field of view are analyzed. We introduce transmission functions relating the received radiant power to reference power levels relevant to two different experimental situations. In the first case, the transmission function relates the received power to a reference power level appropriate to a nonattenuating medium. In the second case, the reference power level is established by bringing the receiver to the close-up position with respect to the source. To examine the effect of the variation of the detector field of view the behavior of the gain factor is studied. Numerical results modeling the laser beam propagation in fog, cloud, and rain are presented.
