| 摘 要： | 在实验的基础上提出了一种用激光后向散射信号的幅度谱进行探测和识别气泡的新
途径。通过对后向散射光信号的幅度谱分析,根据静水与气泡幕的散射信号谱线的不同,可较好地识别气泡,对气泡后向散射较弱的信号该方法也同样适用。

| Abstract: | A new method is proposed for detecting bubbles in this paper based on experiments.After the spectral analysis of back scattering we can identify the bubbles by the differences between bubbles and water.To those feeble back scattering signals the capability of detecting bubbles can also be enhanced by increasing the SNR. |
