| 摘 要： | 为了研究水下气泡幕对激光传输特性的影响,采用米氏散射理论对水下气泡的消光截面和消光系数进行了计算,并在此基础上采用朗伯特-比尔定律对水下气泡幕的消光特性进行了理论分析和实验验证,取得了不同密度、不同厚度以及处于不同位置处气泡幕的透射光功率数据。结果表明,透过气泡幕的光功率随气泡密度以及气泡幕厚度呈指数衰减,而与气泡幕所处的位置没有密切关系。这一结论对舰船气泡尾流的光学探测是有帮助的。

| Abstract: | The extinction section and the extinction efficiency of a bubble are calculated by Mie scattering theory in order to analyze the power of transmission light from a bubble film. A formula is deduced by the Lambert-Beer law for calculating the power. The power of transmission light from various densities, thicknesses, and distances was measured by a power meter. The results indicate that the power decays exponential with the densities and the thicknesses, but bears no relation to the distances between the film and the detector. |
