摘　　要：分别采用光在水下的传输理论以及Mie光散射理论对水体和气泡幕的后向光散射特性进行分析,发现它们在空间分布上存在不同。水体的后向光散射在空间分布上是单调递减的平滑曲线,而气泡幕的则呈现复杂的变化。据此提出了一种新的水下气泡幕激光后向探测方法。该方法通过多元探测器对后向散射光信号进行接收,通过空间分析实现对气泡幕的探测。实验结果表明,该方法可实现对水下气泡幕尤其是远距离气泡幕的有效探测。Based on the theory of light transmission in water and Mie light scattering theory, the light backward scattering properties of water and bubble films were analyzed and they differed from space distribution. The curve of light backward scattering space distribution of water is smoothish and monotonic decreasing, but the curve of bubble film showed complex variety. A new method for laser backward detection bubble films in water was brought forward. Multi-detector were used to receive the backward scattering ...
